The efficient copper-catalyzed cyanoalkylation of amines via C-C bond cleavage has been demonstrated. Distinctive features of this procedure involves mild conditions, broad range of nitrogen nucleophiles, high selectivity, and good functional group tolerance, thus providing a useful approach for the C(sp3)-N bond formations. Most importantly, this protocol is applicable to the late-stage functionalization of natural products, amino acid esters, and drugs. Mechanistic studies suggest that a radical intermediate was involved in this transformation.

Promising anticancer compounds of the type 1,6-disubstituted 4,5,6,7-tetrahydropyrazolo[3,4-c]pyridin-7-ones were identified. The target compounds were readily synthesized in a large scale via a sequence of reactions starting from the commercially available primary amines. Their in vitro anti-proliferative activity has been evaluated on prostate (DU-145), colon (HT-29 and HCT-116) and melanoma (A375P) human cancer cell lines. The relationships between the structure and the anticancer activity, covering all tested cancer cell lines, revealed that the compound 5c with 2,4-dimethylphenyl substituent at R2 was the most potent with the IC50 values in the range as low as 0.16 to 0.40 μM.
Synthesis of 2-[(arylmethylene)amino]cyclopropanecarbonitriles via a two-step ring transformation of 2-(cyanomethyl)aziridines

Reaction of 2-(cyanomethyl)aziridines with N-bromosuccinimide in dichloromethane results in the formation of 3-[(arylmethylene) amino]-4-bromobutanenitriles in high yield. The latter α-amino-γ- bromobutanenitriles were converted into separable trans- and
