title: Concise synthesis of indole-fused 1,4-diazepines through copper(I)-catalyzed domino three-component coupling-cyclization-N-arylation under microwave irradiation.
abstract: Indole-fused benzo-1,4-diazepines were synthesized by copper-catalyzed domino three-component coupling-indole formation- N-arylation under microwave irradiation from a simple N-mesyl-2-ethynylaniline. This method was also applicable to the formation of heterocycle-fused 1,4-diazepines.
