, p. 59 - 68 (2019/01/18)
Synthesis of new 1-(6-chloropyridazin-3-yl)-3-H/alkyl-4-phenyl-1H-pyrazol-5-amines (3) was accomplished by the reaction of 3-chloro-6-hydrazinopyridazine (1) with differently substituted β-ketonitriles (2) under reflux in ethanol. Subsequently, a series of 6-amino derivatives (4, 5 and 6) was synthesized by amino-de-halogenation of 3 with secondry cyclic amines e.g. pyrrolidine, piperidine and morpholine respectively. Structures of all the compounds were established by IR, NMR (1H, 13C and 19F) and mass spectral data, and elemental analysis. All the compounds were screened for their cytotoxic effects against three cancer cell lines (SB-ALL, NALM-6, MCF-7) using colorimetric MTT assay.
Copper-catalyzed N-aryl-β-enaminonitrile synthesis utilizing isocyanides as the nitrogen source

, p. 1004 - 1012 (2015/03/30)
A novel synthetic protocol for N-aryl-β-enaminonitriles, which are useful building blocks for heterocycle synthesis, was developed using isocyanides as the nitrogen source. Using copper-catalyzed one-step reactions between isocyanides and benzyl cyanides under mild conditions, diverse N-aryl-β-enaminonitriles could be synthesized in excellent yields and with high atom-efficiency. N-Alkyl-β-enaminonitriles were also synthesized in good yields. A mechanism involving an imidoyl-copper intermediate was proposed based on mechanistic studies and previous reports. In addition, we demonstrated that a synthesized N-aryl-β-enaminonitrile could be utilized for the synthesis of a β-keto nitrile compound and 3-aminopyrazole.

α-Cyano aldehydes undergo selective transition-metal-catalyzed monoallylation to provide α-allylated nitriles. The transformation leads to linear substitution products with palladium catalysts or branched allylated nitriles using an iridium catalyst. Faci
β-Amination of saturated nitriles through palladium-catalyzed dehydrogenation, 1,4-addition, and re-dehydrogenation

Amination at the β-position of 2-arylpropionitriles through catalytic dehydrogenation occurred by using [PdCl2(PMe3) 2] catalyst and bromobenzene. This is the first catalytic reaction involving the direct dehydrogenation of saturated nitriles.

We describe a novel 7-aminopyrazolo[1,5-a]pyrimidine (7-APP) derivative as a potent hepatitis C virus (HCV) inhibitor. A series of 7-APPs was synthesized and evaluated for inhibitory activity against HCV in different cell culture systems. The synthesis and preliminary structure-activity relationship study of 7-APP are reported.
