Abstract

Difluorocarbene, generated in situ from chlorodifluoroacetate via decarboxylation, reacts efficiently with primary amines to produce isocyanides. Various primary amines can be converted, including aryl, heteroaryl, benzyl, and alkyl amines, as well as amine residues in amino acids and peptides. Late-stage functionalization of biologically active amines is also demonstrated.
