A one-pot synthesis of benzoyl-substituted fused pyrroles or indoles in moderate to high yields has been achieved by the photocyclization/photohydrolysis reactions of N-(ω-phenylalkynyl)-2-chloropyrrole-3-carbaldehydes or 3-acyl-N-(ω-phenylbutynyl)-2-haloindoles in wet acetone. The formation of all these products could be inferred by a two-step reactions, namely, photoinduced chlorine atom-transfer
到高收率苯甲酰基取代的稠合的吡咯或吲哚在温和的一锅法合成已由的photocyclization / photohydrolysis反应实现Ñ(ω-phenylalkynyl)-2-氯代吡咯-3- carbaldehydes或3-酰基- ñ -湿态的(ω-苯基丁炔基)-2-卤代吲哚丙酮。所有这些产物的形成可以通过两步反应来推断,即光诱导的氯原子转移环化和随后的光水解。
