Abstract

This review summarizes methods of N-functionalization of imidazole and its derivatives through simple aza-Michael addition. Apart from advances in the development of efficient additives applied for this transformation, examples of this reaction’s applicability in the synthesis of biologically relevant molecules are presented.
