Guan, Zhenhong published the artcileA highly efficient catalyst for Suzuki-Miyaura coupling reaction of benzyl chloride under mild conditions, Category: nitriles-buliding-blocks, the publication is RSC Advances (2014), 4(69), 36437-36443, database is CAplus.

Diarylmethane derivatives, were synthesized in Suzuki-Miyaura coupling reaction of benzyl chloride with arylboronic acids. Pd(II) organometallic catalysts immobilized on the triphenylphosphine-functionalized microporous knitting aryl polymer (KAPs(Ph-PPh₃)-Pd) as a novel heterogeneous catalyst was employed in Suzuki-Miyaura coupling reaction of benzyl chloride and exhibited excellent catalytic activity under mild conditions with a turnover frequency (TOF) up to 76 min^-1 (4569 h^-1). This work reveals that the microporous structure of the catalyst can rapidly adsorb substrates, consequently facilitating their interaction, and eventually promoting the catalytic efficiency.

Gallardo-Fuentes, Sebastian published the artcileInfluence of Non-Covalent Interactions in the Exo- and Regioselectivity of Aza-Diels-Alder Reactions: Experimental and DFT Calculations, Application In Synthesis of 5153-73-1, the publication is Journal of Organic Chemistry (2019), 84(17), 10825-10831, database is CAplus and MEDLINE.

A systematic exptl. and theor. study of the intermol. aza-Diels-Alder reaction using 5-aminopyrrole as a building block shows that the commonly accepted endo selectivity, ruled by controversial secondary orbital interactions, are overcome by non-covalent interactions affording the unusual exo adduct. Addnl., the regioselectivity is also influenced by such interactions. The starting materials are easily prepared, and the use of water as the solvent is a great achievement for the development of cleaner synthetic methodologies.

Yang, Mu published the artcileToll-like receptor 7 and 8 imidazoquinoline-based agonist/antagonist pairs, Synthetic Route of 5098-14-6, the publication is Bioorganic & Medicinal Chemistry Letters (2022), 128548, database is CAplus and MEDLINE.

Toll-like receptors (TLRs) 7 and 8 are key targets in the development of immunomodulatory drugs for treating infectious disease, cancer, and autoimmune disorders. These receptors can adopt both agonist and antagonist binding conformations that switch the receptor signal on or off to the downstream production of cytokines. In this study, we examined the effect of simple isomeric substitutions to the C2-Bu group of two imidazoquinoline agonists and evaluated the activity of these analogs using both TLR7 and TLR8 reporter cells and cytokine induction assays. the C2-iso-Bu and C2-cyclopropylmethyl isomers are both mixed TLR7/8 competitive antagonists of the parent agonist [4-Amino-1-(4-(aminomethyl)benzyl)-2-butyl-7-methoxycarbonyl-1H-imidazo[4,5-c]quinoline], indicating the conformation of the dimeric receptor complex is highly sensitive to steric perturbations to the ligand binding pocket. This observation is consistent with prior work demonstrating TLR7 and TLR8 activity is directly correlated to C2-alkyl substitutions that project into a hydrophobic pocket at the dimer interface of the receptor. The close structural relationship of the agonist/antagonist pairs identified here highlights the importance of this pocket in tipping the balance between the agonist and antagonist binding states of the receptor which may have significant ramifications to the design of imidazoquinoline-based immunomodulatory agents.

Bakke, J. E. published the artcileMetabolism of 2,6-dichlorobenzonitrile, 2,6-dichlorothiobenzamide in rodents and goats, Application In Synthesis of 3336-34-3, the publication is Xenobiotica (1988), 18(9), 1063-75, database is CAplus and MEDLINE.

Twelve ¹⁴C-labeled metabolites were isolated from either urine or bile from either rats (11 metabolites) or goats (7 metabolites) given single oral doses of 2,6-dichlorobenzo[¹⁴C]nitrile (DCBN). Five of these metabolites were also excreted in urine from rats dosed orally with 2,6-dichlorothiobenz[¹⁴C]-amide (DCTBA). All metabolites from either DCBN or DCTBA were benzonitriles with the following ring substituents: Cl₂, OH (three isomers); Cl₂, (OH)₂; Cl, (OH)₂; Cl, OH, SH; Cl, OH, SCH₃; SCH₃, SOCH₃, OH; Cl₂, S-(N-acetyl)cysteine; Cl, S-(N-acetyl)cysteine; Cl, OH, S-(N-acetyl)cysteine. The thiobenzamide moiety of DCTBA was converted to the nitrile in all the excreted urinary metabolites. No hydrolysis of the nitrile in DCBN to either an amide or an acid was detected. Urine was the major route for excretion; however, enterohepatic circulation occurred. Whole-body autoradiog. of ¹⁴C-DCBN and ¹⁴C-DCTBA in mice showed the presence of bound residues in the mucosa of the nasal cavity, trachea, tongue, esophagus, the kidney, liver, and the intestinal contents.

Reilly, Sean W. published the artcileLate-Stage Carbon Isotope Exchange of Aryl Nitriles through Ni-Catalyzed C-CN Bond Activation, Related Products of nitriles-buliding-blocks, the publication is Journal of the American Chemical Society (2021), 143(12), 4817-4823, database is CAplus and MEDLINE.

A facile one-pot strategy for ¹³CN and ¹⁴CN exchange with aryl, heteroaryl, and alkenyl nitriles using a Ni phosphine catalyst and BPh₃ is described. This late-stage carbon isotope exchange (CIE) strategy employs labeled Zn(CN)₂ to facilitate enrichment using the nonlabeled parent compound as the starting material, eliminating de novo synthesis for precursor development. A broad substrate scope encompassing multiple pharmaceuticals is disclosed, including the preparation of [¹⁴C] belzutifan to illustrate the exceptional functional group tolerance and utility of this labeling approach. Preliminary exptl. and computational studies suggest the Lewis acid BPh₃ is not critical for the oxidative addition step and instead plays a role in facilitating CN exchange on Ni. This CIE method dramatically reduces the synthetic steps and radioactive waste involved in preparation of ¹⁴C labeled tracers for clin. development.

Wang, Bing published the artcileNovel axial substituted subphthalocyanines and their TiO2 nanocomposites: Synthesis, structure, theoretical calculation and their photocatalytic properties, Recommanded Product: Phthalonitrile, the main research area is titanium dioxide nanocomposite electronic transition photocatalytic property.

For the study, we reported the synthesis and characteristics of two subphthalocyanines H12SubPcB-Br (SubPc-1) and H12SubPcB-OPh2OH (SubPc-2), in addition to their resp. composites with nano-titanium dioxide (TiO2). SubPc-1 and SubPc-2 were composed by the measure of hydrotherm with toluene on the scene. The approaches of DFT and TD-DFT were used to research the electronic structure and optical spectra in the subphthalocyanines. The photocatalytic activities of pristine TiO2 particle and TiO2/SubPc composites went through the test to degrade methyl orange (MO) and bromophenol blue (BB) in irradiance of visible light. It is demonstrated from the results that all the TiO2/SubPc photocatalysts exhibited further improved efficiency approx. 72.4% and 29.2% for the degradation of MO and BB under visible light, in comparison with pure TiO2. Furthermore, the reusability studies showed that photocatalytic activity could be maintained over 84% after five recycles.

Walden, Melissa T. published the artcileHomoleptic platinum(II) complexes with pyridyltriazole ligands: excimer-forming phosphorescent emitters for solution-processed OLEDs, Category: nitriles-buliding-blocks, the main research area is platinum complex pyridyltriazole ligand phosphorescent emitter OLED solution processing.

Two new homoleptic platinum(II) complexes are reported that feature aryl-appended 5-(2-pyridyl)-1,2,4-triazole chelates acting as NN̂- ligating ions, PtL12 and PtL22. Readily prepared from easily accessible proligands, they offer good solubility in organic solvents, allowing them to be incorporated into OLEDs through solution processing. Crystal structures reveal staggered, face-to-face packing of the π systems in adjacent complexes, but with no close Pt···Pt interactions. The complexes display bright unimol. phosphorescence: for PtL12 and PtL22 resp., λmax = 502 and 514 nm; Φ = 0.21 and 0.48; τ = 5.1 and 4.6 μs in deoxygenated CH2Cl2 at 295 K. Both complexes show a strong propensity to form intensely emissive excimers at higher concentrations: λmax = 585 and 625 nm for PtL12 and PtL22. The photophys. properties in doped and neat thin films have been investigated using steady-state and time-resolved methods. These studies highlight the presence of different environments of bimol. excited states with different lifetimes, those emitting at lowest energy apparently having the longest lifetimes, contrary to what is normally found for unimol. emitters through the effects of vibrational deactivation. The prototype solution-processed OLEDs gave EQEs of 9.6-12.5% for PtL12 and 8.8-11.4% for PtL22, impressive values for solution-processed devices incorporating such simple complexes and only a little inferior to the EQE of 15% achieved using PtL12 in a device prepared by evaporation Compounds of this type have potential to provide the red and green components for white light OLEDs, due to their tunable, uni- and bimol. excited state emission.
