A cyanide‐free platform technology for the synthesis of chiral nitriles by biocatalytic enantioselective dehydration of a wide range of aldoximes is reported. The nitriles were obtained with high enantiomeric excess of >90 % ee (and up to 99 % ee) in many cases, and a “privileged substrate structure” with respect to high enantioselectivity was identified. Furthermore, a surprising phenomenon was observed

A general and chemoselective catalytic alkylation of nitriles using a homogeneous nonprecious manganese catalyst is presented. This alkylation reaction uses naturally abundant alcohols and readily available nitriles as coupling partners. The reaction tolerates a wide range of functional groups and heterocyclic moieties, efficiently providing useful cyanoalkylated products with water as the only side
thiocyanates to generate α-arylthioalkanenitriles bearing sulfur-substituted quaternarycarboncenter atoms has been described. This novel protocol involves the procedure of copper carbene species promoting S–CN bond cleavage and C–CN/C–S bond reconstruction to introduce both sulfur and cyano groups onto a single carboncenter. This cyanothiolation reaction will greatly enhance the synthetic utility of
