Chen, Ying-Chu published the artcileC-N Coupling of DNA-Conjugated (Hetero)aryl Bromides and Chlorides for DNA-Encoded Chemical Library Synthesis, Quality Control of 1885-29-6, the main research area is DNA encoded heteroaryl amide library synthesis.

DNA-encoded chem. library (DECL) screens are a rapid and economical tool to identify chem. starting points for drug discovery. As a robust transformation for drug discovery, palladium-catalyzed C-N coupling is a valuable synthetic method for the construction of DECL chem. matter; however, currently disclosed methods have only been demonstrated on DNA-attached (hetero)aromatic iodide and bromide electrophiles. We developed conditions utilizing an N-heterocyclic carbene-palladium catalyst that extends this reaction to the coupling of DNA-conjugated (hetero)aromatic chlorides with (hetero)aromatic and select aliphatic amine nucleophiles. In addition, we evaluated steric and electronic effects within this catalyst series, carried out a large substrate scope study on two representative (hetero)aryl bromides, and applied this newly developed method within the construction of a 63 million-membered DECL.

Du, Hong-Quan published the artcileBicyclic Bridgehead Phosphoramidite-Based Hybrid Diphosphorus Ligands: Design, Synthesis, and Application in Catalytic Asymmetric Hydrogenation, COA of Formula: C7H6N2, the main research area is bicyclic bridgehead phosphoramidite hybrid diphosphorus ligand preparation; arylethyl acetanilide preparation enantioselective; vinylanilide asym hydrogenation rhodium catalyst.

A strategy for chiral ligand design has been developed that allows for incorporation of an achiral bicyclic bridgehead phosphoramidite to generate a class of hybrid diphosphorus ligands for high activity and asym. control. Using this concept, a series of chiral phosphine-phosphoramidite ligands bearing the sole chirality at the ligand backbone have been prepared and successfully employed in the Rh-catalyzed asym. hydrogenation of 2-vinylanilides for the synthesis of optically active anilines bearing an ortho-tertiary benzylic stereocenter.

Magli, Elisa published the artcileSynthesis, docking studies, and pharmacological evaluation of 5HT2C ligands containing the N’-cyanoisonicotinamidine or N’-cyanopicolinamidine nucleus, Computed Properties of 100-70-9, the main research area is cyanoisonicotinamidine cyanopicolinamidine depression antidepressant anxiety anxiolytic psychosis antipsychotic 5HT2C; 5-HT1A, 5-HT2A, and 5-HT2C ligands; arylpiperazine derivatives; behavioral tests; binding assays, in vitro assay.

N’-Cyanoisonicotinamidine and N’-cyanopicolinamidine derivatives, linked to an arylpiperazine moiety, were prepared and their affinities to the 5-HT1A, 5-HT2A, and 5-HT2C receptors were evaluated. Several of the newly synthesized compounds, tested by binding studies, showed nanomolar affinity at the 5-HT1A and 5-HT2C receptors and moderate or no affinity for other relevant receptors (D1, D2, α1, and α2). Compound 8e(I) (Ki = 21.4 nM) was the most affine for the 5-HT2C receptor, showing, at the same time, a high selectivity with respect to the other receptors analyzed. Compounds 4a(II) and 4c(III), instead, showed an interesting mixed 5-HT1A/5-HT2C activity with Ki values of 21.3/11.5 and 23.2/6.48 nM, resp. The compounds with better affinity and selectivity binding profiles toward 5-HT2C (I, II, III, and 8b(IV)) were selected for further in vivo assays to determine their functional activity. Finally, to rationalize the obtained results, mol. docking studies were performed. The results of the pharmacol. studies showed that compounds I, II, and IV exerted antidepressant-like effects and I and II revealed also significant anxiolytic properties. Among the developed derivatives, the most promising compound seems to be II, which displayed antipsychotic-, antidepressant- and anxiolytic-like properties. No side effects, like catalepsy, motor-impairment or ethanol-potentiating effects, were observed after the injection of the tested compounds

Huamani, Luis Enrique Santa Cruz published the artcileRole of Protonation and Isomerism in the Supramolecular Architectures of Heteroaryl-2-imidazole Compounds: Crystal Packing Patterns and Energetics, Name: Picolinonitrile, the main research area is azaarylimidazole isomer crystal structure packing protonation.

The influence of isomerism and protonation on crystal packing patterns of three isomeric heteroaryl-2-imidazoles and one related compound was investigated by using single-crystal X-ray diffraction and d. functional theory. The comparison of their crystal structures helped unveil the details of the energetic balance controlling supramol. packing and an unprecedented supramol. synthon. The neutral species were featured by a whole crystal close packing like a herringbone pattern, which was mainly favored by C-H···π interactions. On the other hand, the crystal packing of the protonated species was characterized by π-stacking layers being supported by π···π and anion-π interactions. Energy framework anal. revealed that both Coulombic interactions between hydrogen bond chains and dispersion energies mainly contributed to the stabilization of the herringbone pattern assembly, whereas a predominant contribution from Coulombic energy frameworks to total energy in protonated forms was observed The different patterns displayed pieces of evidence of not only the important participation of the heteroaryl moieties in the supramol. assembly but also the significant contribution of protonation hampering the N-H···N hydrogen bonding interactions in the imidazole group. A thorough characterization of the compounds by means of thermogravimetric anal., differential scanning calorimetry, Fourier-transform IR spectroscopy, NMR, and electrospray ionization-(+)-MS is also presented. The most characteristic crystal packing patterns of a series of N-heteroaryl-2-imidazole systems has been observed and analyzed. Neutral forms tend to pack in a herringbone pattern, whereas protonated forms tend to pack in parallel π-stacked layers. The imidazole fragments dominate the construction of the supramol. architectures through complex hydrogen bond networks. An unprecedented supramol. synthon was also found for one of the supramol. arrangements, and the energetics involved in the crystal packings was also assessed by theor. methods.

Novel synthetic approach to low-symmetry meso-Ph substituted tetrabenzoporphyrins (TPBs) by Zn(OAc)2 templated assembly of phthalonitrile in the presence of benzyltriphenylphosphonium chloride has been proposed affording two main products: 5-phenyl-21H,23H-TBP (I) and 5,10-diphenyl-21H,23H-TBP (II) with higher yield for compound I. Procedure for isolation of I and II in individual high purity state has been developed supplemented with selection of an appropriate NMR solvent system (CDCl3 with 1% additive of CF3COOH) that allowed full signal assignment in 1H and 13C spectra to be made utilizing homonuclear 1H-1H (COSY, NOESY, TOCSY) and heteronuclear 1H-13C (HSQC) correlation techniques. Isolation and physicochem. study of a mixture of monobenzylated co-products were carried out as well involving 1D and 2D NMR spectroscopies, which for the first time allowed not only to find out their structure, but also to determine the ratio of the positional isomers formed.

Chen, Ying published the artcileAssembly of α-(Hetero)aryl Nitriles via Copper-Catalyzed Coupling Reactions with (Hetero)aryl Chlorides and Bromides, Formula: C16H13NO, the main research area is aryl heteroaryl nitrile synthesis; copper catalyzed coupling decarboxylation aryl heteroaryl halide cyanoacetate; C−C cross-coupling; anti-inflammatory drugs; copper; oxalamide ligands; α-(hetero)aryl nitriles.

α-(Hetero)aryl nitriles are important structural motifs for pharmaceutical design. The known methods for direct synthesis of these compounds via coupling with (hetero)aryl halides suffer from narrow reaction scope. Herein, we report that the combination of copper salts and oxalic diamides enables the coupling of a variety of (hetero)aryl halides (Cl, Br) and Et cyanoacetate under mild conditions, affording α-(hetero)arylacetonitriles via one-pot decarboxylation. Addnl., the CuBr/oxalic diamide catalyzed coupling of (hetero)aryl bromides with α-alkyl-substituted Et cyanoacetates proceeds smoothly at 60°C, leading to the formation of α-alkyl (hetero)arylacetonitriles after decarboxylation. The method features a general substrate scope and is compatible with various functionalities and heteroaryls. Thus, e.g., 4-chloroanisole + Et cyanoacetate → 2-(4-methoxyphenyl)acetonitrile (up to 80%).

Mashweu, Adelaide R. published the artcileSubstrate profiling of the cobalt nitrile hydratase from Rhodococcus rhodochrous ATCC BAA 870, Name: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is substrate profiling cobalt nitrile hydratase Rhodococcus rhodochrous ATCCBAA 870; biocatalysis; carboxamide; green chemistry; nitrile hydratase.

The aromatic substrate profile of the cobalt nitrile hydratase from Rhodococcus rhodochrous ATCC BAA 870 was evaluated against a wide range of nitrile containing compounds (>60). To determine the substrate limits of this enzyme, compounds ranging in size from small (90 Da) to large (325 Da) were evaluated. Larger compounds included those with a bi-aryl axis, prepared by the Suzuki coupling reaction, Morita-Baylis-Hillman adducts, heteroatom-linked diarylpyridines prepared by Buchwald-Hartwig cross-coupling reactions and imidazo[1,2-a]pyridines prepared by the Groebke-Blackburn-Bienayme multicomponent reaction. The enzyme active site was moderately accommodating, accepting almost all of the small aromatic nitriles, the diarylpyridines and most of the bi-aryl compounds and Morita-Baylis-Hillman products but not the Groebke-Blackburn-Bienayme products. Nitrile conversion was influenced by steric hindrance around the cyano group, the presence of electron donating groups (e.g., methoxy) on the aromatic ring, and the overall size of the compound

Mikshiev, Vladimir Y. published the artcileperi-Interactions in 1,8-bis(dimethylamino)naphthalene ortho-ketimine cations facilitate [1,5]-hydride shift: selective synthesis of 1,2,3,4-tetrahydrobenzo[h]quinazolines, Recommanded Product: Picolinonitrile, the main research area is selective tetrahydrobenzoquinazoline preparation density functional theory; bis dimethylamino naphthalene ketimine heterocyclization.

Selective heterocyclization leading to 1,2,3,4-tetrahydrobenzo[h]quinazolines I (R1 = H, Br; R2 = Ph, n-Bu, furan-2-yl, etc.) from ortho-ketimines of 1,8-bis(dimethylamino)naphthalene (DmanIms) II under acid catalysis has been revealed. In contrast to the rather unreactive N,N-dimethylaniline ortho-ketimine II, DmanIms readily undergo this transformation without an addnl. catalyst. This distinction in the reactivity underscores the importance of the second peri-NMe2 group in DmanIms, which facilitates a [1,5]-hydride shift and the subsequent cyclization. The cascade of peri-interactions emerging between 1-NMe2 and 8-NMe2 groups has been identified as a reason for the catalytic effect: (1) the hydrogen bond in the DmanIm dication constrains 1-NMe2 in the desired position providing proximity of reaction centers, (2) the repulsion of the lone pairs of 8-NMe2 group and unrelaxed 1-NMe2 group arising right after deprotonation process reduces the Gibbs free energy of activation (ΔG) for the straight hydride shift, and (3) the electrostatic interaction between 8-NMe2 and the charged N=CH2+ group in the intermediate increases the ΔG for the reverse hydride shift.
