A metal-free aminoarylation of internal alkynes is described, yielding tetrasubstituted enaminoates. The transformation proceeds in good to excellent yields through a tandem conjugate addition/Smiles rearrangement involving aryl and heteroaryl sulfonamides. Substrate scope is very broad under simple, user-friendly conditions, and the reaction can be used to easily access biologically active phenethylamine derivatives.
本文描述了一种无金属的芳基炔烃的氨基芳基化反应，生成了四取代的烯胺酸酯。该转化通过串联的共轭加成/Smiles 重排反应，涉及芳基和杂芳基磺酰胺，以良好至优秀的收率进行。在简单、用户友好的条件下，底物的适用范围非常广泛，并且该反应可用于轻松获得生物活性的苯乙胺衍生物。
