Reductive amidation of alkyl tosylates with isocyanates by a Ni/Co-dual catalytic system

Chem Commun (Camb). 2020 Jan 28;56(8):1247-1250. doi: 10.1039/c9cc09377j.

Abstract

Reductive amidation of alkyl tosylates with isocyanates using the Ni/Co-dual catalytic system is disclosed. The method proceeds efficiently under mild conditions, giving rise to the corresponding alkyl amides. Notably, the protocol can discriminate the steric environment of two alkyl tosylate moieties, enabling regioselective mono-amidation at the less-bulky site.
