The directamination of cyanohydrins with amines via a catalytic cyano-borrowing reaction was developed. The transformation features broad substrate scope, excellent functional group compatibility, and very mild and simple operations. Moreover, a titanium catalyst supported by quinine and (S)-BINOL ligands enabled an asymmetric cyano-borrowing reaction with moderate to high enantioselectivity.
An Ecofriendly and Efficient Approach through Sodium Oxalate Catalyst for the
Synthesis of Azomethines and α-Aminonitriles Ligands Employing Aqueous Medium
An ecofriendly, efficient, inorganic salt catalyzed facile method has been developed for the synthesis of potential ligands azomethines and α-aminonitriles employing aqueous medium. This procedure involves the use of Zn(CN)2 an inexpensive, less toxic as compared to KCN, ecofriendly and readily available effective cyanide source. Cyanated products specially have been isolated in high yield on usual

An efficient and eco-friendly method has been developed for the synthesis of alpha-aminonitriles via one-pot three-component condensation of carbonyl compounds, amines, and Zn(CN)(2) under mild conditions. This protocol has the features of use of inexpensive, ecofriendly readily available, effective cyanide source, high yield, and simple work-up procedure. (C) 2011 Elsevier Ltd. All rights reserved.
