An effective method for aminoacylation of indoles and pyrroles has been achieved. The transformation involves a multicomponent one-pot cascade reaction between indoles or pyrroles, ynol ethers, and sulfonyl azides, creating four different bonds regioselectively through N-sulfonyltriazole intermediates. The oxo-tryptamines and oxo-pyrroloethanamines are generated in moderate to high yields under mild
已经实现了吲哚和吡咯氨酰化的有效方法。该转化涉及吲哚或吡咯、炔醇醚和磺酰叠氮化物之间的多组分一锅级联反应,通过 N-磺酰基三唑中间体区域选择性地产生四种不同的键。在温和的反应条件下,以中等至高产率生成氧代色胺和氧代吡咯烷胺。
