Abstract

A Cu te couple: A synthetically useful protocol for the preparation of N-alkynylated sulfoximines (yne sulfoximines) has been developed. The method involves a mild copper-catalyzed oxidative cross-coupling of NH-sulfoximines and terminal alkynes (see scheme). The corresponding N-acyl sulfoximines were also obtained selectively after acid-catalyzed hydrolysis of the yne sulfoximines.
