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 cyclization and subsequent photohydrolysis.
一锅法合成苯甲酰取代的稠合吡咯或吲哚，产率中等至高产，由 N-(ω-苯乙炔基)-2-氯吡咯-3-甲酰基或 3-酰基-N-(ω-苯丁炔基)-2-卤代吲哚在湿丙酮中的光环化/光水解反应实现。所有这些产物的形成都可以通过两步反应推断出来，即光诱导氯原子转移环化和随后的光水解。
