The partial reduction of pyrroles is not a common practice even though it offers a potential route to pyrroline building blocks, commonly used for synthesis. We have investigated the reduction of 2-acyl-N-sulfonylpyrroles and by varying the hydride source and solvent, achieved a chemoselective reduction, leading to 3-pyrrolines and alkyl pyrroles in high yield.
吡咯的部分还原并不是一种常见的实践,尽管它提供了一条潜在的途径来合成常用于合成的吡咯啉构建块。我们研究了2-酰基-N-磺酰吡咯的还原,通过改变氢化剂来源和溶剂,实现了化学选择性还原,得到高产率的3-吡咯啉和烷基吡咯。
