gem-Bromonitrocyclobutane induced radical cyclization of acrylanilides to construct 2-oxindolesviaphotoredox catalysis

Abstract

A mild and efficient method concerning tandem radical reactions of gem-bromonitroalkanes with various acrylanilides was reported. 2-Oxindoles with a 1-nitrocyclobutyl unit, otherwise hard to prepare, were easily obtained in good...
