A general protocol for stereoselective construction of enaminyl sulfonyl fluorides†

Abstract

A simple, efficient, and mild reaction of 2-chloroprop-2-ene-1-sulfonyl fluoride (CESF) with amines was developed, affording a variety of highly functionalized enaminyl sulfonyl fluorides in good to excellent yields (56–96%). This transformation features a broad substrate scope, high atom economy, operational simplicity and up to 100% stereoselectivity, which can provide great application value in medicinal chemistry, chemical biology, and drug discovery.
