Abe, Takumi; Noda, Kenta; Sawada, Daisuke published the artcile< Synthesis of α-substituted indolylacetamide using acetonitriles as acetamide enolate equivalents through O-transfer reactions>, Application In Synthesis of 21667-62-9, the main research area is indolylacetamide preparation; ammonium hemiaminal acetonitrile alkylation oxygen transfer reaction.

Authors introduce readily available ammonium hemiaminals as O-transfer reagents and com. available acetonitriles as a primary amide enolate precursor. The combination serves as an amide enolate equivalent, thereby providing one-pot access to α-substituted indolylacetamides I (EWG = COOMe, SO2Me, C(O)Ph, etc.; R1 = H, Ph). A broad substrate scope and good functional group tolerance as well as gram-scale synthesis make this protocol highly attractive. Mechanistic experiments suggest that the cyano group is trapped by a hydroxy group of hemiaminals en route to the desired primary amides under metal-free conditions.

Hattori, Yohei; Nishikawa, Michihiro; Kusamoto, Tetsuro; Kume, Shoko; Nishihara, Hiroshi published the artcile< Steric interference on the redox-conjugated pyrimidine ring rotation of mono- and dinuclear copper complexes with (4-methyl-2-pyrimidinyl)imine ligands>, Application of C6H11NO2, the main research area is copper phenanthroline methylpyrimidinylmethylene benzeneamine complex preparation; electrochem copper phenanthroline methylpyrimidinylmethylene benzeneamine complex; crystal structure copper phenanthroline methylpyrimidinylmethylene benzeneamine complex.

A mononuclear copper(I) complex with N-[(4-methyl-2-pyrimidinyl)methylene]-p-toluidine (1·BF4; [(Phen-anth2)Cu(L1)]·BF4) and a dinuclear copper(I) complex with N,N’-bis[(4-methyl-2-pyrimidinyl)-methylene]-p-phenylenediamine (2·(BF4)2; [(Phen-anth2)2Cu2(μ-L2)]·(BF4)2) (where Phen-anth2 = dianthracenylphenathroline, L1 = N-[(4-methyl-2-pyrimidinyl)methylene]-p-toluide and L2 = N,N’-bis[(4-methyl-2-pyrimidinyl)methylene]-p-phenylenediamine) were synthesized as BF4- salts to evaluate the influence of the imine moiety on the pyrimidine ring rotation isomerism. 1·BF4 existed in solution as a mixture of two isomers; 2·(BF4)2 was present as a mixture of three isomers. The redox potentials of the copper centers were changed by pyrimidine ring rotation. Comparison of 1+ and 22+ indicated that increasing the steric congestion around the copper center increased the o/i isomer ratio; the redox potentials of both the o- and i-isomers shifted in the pos. direction, and the CuII/I redox reaction became slower.

Perry; Cuozzo, John W.; Lin, Lih-Ling published the artcile< Inhibitors of Tumor Progression Loci-2 (Tpl2) Kinase and Tumor Necrosis Factor α (TNF-α) Production: Selectivity and in Vivo Antiinflammatory Activity of Novel 8-Substituted-4-anilino-6-aminoquinoline-3-carbonitriles>, COA of Formula: C6H11NO2, the main research area is anilinoaminoquinoline carbonitrile derivative preparation structure Tpl2 kinase inhibitor antiinflammatory.

Tumor progression loci-2 (Tpl2) (Cot/MAP3K8) is a serine/threonine kinase in the MAP3K family directly upstream of MEK. Recent studies using Tpl2 knockout mice have indicated an important role for Tpl2 in the lipopolysaccharide (LPS) induced production of tumor necrosis factor α (TNF-α) and other proinflammatory cytokines involved in diseases such as rheumatoid arthritis. Initial 4-anilino-6-aminoquinoline-3-carbonitrile leads showed poor selectivity for Tpl2 over epidermal growth factor receptor (EGFR) kinase. Using mol. modeling and crystallog. data of the EGFR kinase domain with and without an EGFR kinase-specific 4-anilinoquinazoline inhibitor (erlotinib, Tarceva), the authors hypothesized that the authors could diminish the inhibition of EGFR kinase by substitution at the C-8 position of the 4-anilino-6-aminoquinoline-3-carbonitrile leads. The 8-substituted-4-anilino-6-aminoquinoline-3-carbonitriles were prepared from the appropriate 2-substituted 4-nitroanilines. Modifications to the C-6 and C-8 positions led to the identification of compounds with increased inhibition of TNF-α release from LPS-stimulated rat and human blood, and these analogs were also highly selective for Tpl2 kinase over EGFR kinase. Further structure-activity based modifications led to the identification of 8-bromo-4-(3-chloro-4-fluorophenylamino)-6-[(1-methyl-1H-imidazol-4-yl)methylamino]quinoline-3-carbonitrile, which demonstrated in vitro as well as in vivo efficacy in inhibition of LPS-induced TNF-α production

Bollini, Mariela; Domaoal, Robert A.; Thakur, Vinay V.; Gallardo-Macias, Ricardo; Spasov, Krasimir A.; Anderson, Karen S.; Jorgensen, William L. published the artcile< Computationally-Guided Optimization of a Docking Hit to Yield Catechol Diethers as Potent Anti-HIV Agents>, Product Details of C7H3ClFN, the main research area is catechol ether anti HIV reverse transcriptase inhibitor computational optimization.

A 5-μM docking hit has been optimized to an extraordinarily potent (55 pM) non-nucleoside inhibitor of HIV reverse transcriptase. Use of free energy perturbation (FEP) calculations to predict relative free energies of binding aided the optimizations by identifying optimal substitution patterns for Ph rings and a linker. The most potent resultant catechol diethers feature terminal uracil and cyanovinylphenyl groups. A halogen bond with Pro95 likely contributes to the extreme potency of compound 42 (I). In addition, several examples are provided illustrating failures of attempted grafting of a substructure from a very active compound onto a seemingly related scaffold to improve its activity.

A sequential multi-component reaction of β-ketonitriles with N,N-disubstituted hydrazines is designed and developed through a photocatalyzed intermol. amination process to afford hydrazonamides I [R = Et, Ph, 2-furyl, etc.; R1 = Me, Et, n-Pr, etc.; R2 = Ph, 3-MeC6H4, 4-ClC6H4, etc.]. This work reported the first example of the use of N,N-disubstituted hydrazines as two different “”amine”” sources, characterized by isotope labeling experiments The C-CN/N-N bonds were cleaved and new C-N/C=N bonds were constructed in a one-pot reaction. This protocol could be carried out without the addition of any external metals, ligands, bases, oxidants and reductants, and possessed the advantages of operational simplicity, mild reaction conditions, and good functional group tolerance. Furthermore, this approach enabled late-stage modifications of structurally complex bioactive mols., natural products and drugs, thus showing potential applications in the field of organo-pharmaceutical chem.

An efficient catalytic system of organic base-coupled ionic liquids (ILs) that could catalyze the synthesis of quinazolinones I (R1 = H, OMe, Cl, Br, R2 = H; R1 = H, R2 = Cl) via cyclization of 2-aminobenzonitriles with CO2 under mild conditions (e.g., 60°C, 0.1 MPa) was reported. It was found that 1,8-diazabicyclo[5.4.0]undec-7-ene coupled with 1-butyl-3-methylimidazole acetate ionic liquids, (DBU/[Bmim][OAc]), displayed excellent performance in catalyzing the reactions of CO2 with 2-aminobenzonitriles to give compounds I in high yields at atm. pressure. Moreover, the ILs had high stability and reusability, and could be reused at least five times without considerable decrease in catalytic activity. This protocol could also be conducted on a gram scale, and may have promising and practical applications in the production of quinazolinones.

Ruske, Walter; Becker, Manfred; Jahns, Hans Joachim published the artcile< Polymerization mechanisms of hydrocyanic acid. II. Reaction of negatively disubstituted acetonitriles with ammonia>, Application In Synthesis of 6136-93-2, the main research area is .

Cl2CHCN and NH3 form 2,4,6-tris(dichloromethyl)-1,3,5-triazine and a black-brown polymer (I). Its infrared spectrum coincides with that of the polymer formed from dichloroacetamidine and NH3 and is very similar to the spectrum of paracyanogen. Elementary analysis of I shows the presence of O, probably introduced by hydrolysis. Polymerization of diethoxyacetonitrile, which has a lesser inductive effect of its C-X dipole than the dichloro compound, does not lead to tris(diethoxymethyl)-1,3,5-triazine. These 2 cases permit a general prediction about the course of the polymerization mechanism of HCN. The reaction has the same selectivity towards the catalyst as the benzoin condensation; the real catalyst is the cyanide ion.
