remains an undeveloped area of organic synthesis. Moreover, catalytic activation of this difficult electrophile with predictable stereo-outcomes presents an even more formidable challenge. Described herein is a simple iron-based catalyst system which provides the mild, direct conversion of secondary and tertiary alcohols to sulfonamides. Starting from enantioenriched alcohols, the intramolecular variant
未活化醇的直接催化取代仍然是有机合成的未开发领域。此外,具有可预测的立体结果的这种困难的亲电试剂的催化活化提出了甚至更大的挑战。本文描述了一种简单的铁基催化剂体系,该体系提供了仲和叔醇向磺酰胺的温和,直接的转化。从富含对映体的醇开始,分子内变体进行立体转化以产生富含对映体的2-和2,2-取代的吡咯烷和二氢吲哚,而无需事先衍生化醇或溶剂化条件。
