Concise Synthesis of Indole-Fused 1,4-Diazepines through Copper(I)-Catalyzed Domino Three-Component Coupling−Cyclization−N-Arylation under Microwave Irradiation
摘要:
Indole-fused benzo-1,4-diazepines were synthesized by copper-catalyzed domino three-component coupling-indole formation- Marylation under microwave irradiation from a simple N-mesyl-2-ethynylaniline. This method was also applicable to the formation of heterocycle-fused 1,4-diazepines.
