摘要
Copper-catalyzed three-component and four-component cascade reactions of cyanamides, dirayliodonium triflates, and propargylamine were established for the rapid construction of polysubstituted 2-aminoimidazoles and 2-iminoimidazoles using K2CO3 and pyridine as the base, respectively. Each reaction step was efficiently accelerated by copper, and 3-4 C-N bonds were constructed with excellent regioselectivities and good yields.
