A general procedure for the catalytic hydrogenation of nitriles to primary amines by using a non-noble metal-based system is presented. Co(acac)3 in combination with tris[2-(dicyclohexylphosphino)ethyl]phosphine efficiently catalyzes the selective hydrogenation of a wide range of (hetero)aromatic and aliphatic nitriles to give the corresponding amines.

Aberrant c-Met activation has been implicated in multiple tumor oncogenic processes and drug resistance. In this study, a series of imidazo[4,5-b]pyrazine derivatives was designed and synthesized, and their inhibitory activities were evaluated in vitro. Structure–activity relationship (SAR) was investigated systematically and docking analysis was performed to elucidate the binding mode, leading to the identification of the most promising compound 1D-2 which exhibited significant inhibitory effect on both enzymatic (IC50?=?1.45?nM) and cellular (IC50?=?24.7?nM in H1993 cell line) assays, as well as exquisite selectivity and satisfactory metabolic stability in human and rat liver microsomes.
