Base-controlled copper-catalyzed multi-component cascade reactions of cyanamides, diaryliodonium triflates and propargylamine for rapid assembly of polysubstituted 2-aminoimidazoles and 2-iminoimidazoles

Abstract

Copper-catalyzed three-component and four-component cascade reactions of cyanamides, dirayliodonium triflates, and propargylamine were established for rapid construction of polysubstituted 2-aminoimidazoles and 2-iminoimidazoles using K2CO3 and pyridine as base, respectively. Each...
