Stereoselective Construction of Nitrile‐Substituted Cyclopropanes from 2‐Substituted Ethenesulfonyl Fluorides <i>via</i> Carbon‐Sulfur Bond Cleavage

Abstract

Abstract The intermolecular cyclopropanation of 2‐aryl and 2‐styryl substituted ethenesulfonyl fluorides with active cyano‐containing methylene compounds was described. This reaction proceeds via carbon‐sulfur bond cleavage under metal‐free conditions in up to 99% yield, affording a variety of nitrile‐substituted cyclopropanes with high diastereoselectivity. magnified image
