Unprotected indoles are prepared with the title method, which has a wide scope for alkynes. Excellent regioselectivity was accomplished for aryl–alkyl and alkyl–alkyl disubstituted acetylenes. This reaction features an unusual 1,2 rhodium migration and ring‐contraction‐triggered NN bond cleavage. It allows rapid conversion of the reaction products into several functional molecules.
用标题方法制备未保护的吲哚,该方法广泛用于炔烃。对芳基-烷基和烷基-烷基二取代的乙炔具有出色的区域选择性。该反应具有不寻常的1,2铑迁移和环收缩触发的NN键断裂。它可以将反应产物快速转化为几种功能分子。
