Synthesis of Sulfoximidoyl-Containing Hypervalent Iodine(III) Reagents and Their Use in Transition-Metal-Free Sulfoximidations of Alkynes

Well-defined hypervalent iodine(III) reagents incorporating transferable sulfoximidoyl groups were obtained through ligand exchange reactions of methoxy(tosyloxy)iodobenzene (MTIB) with NH sulfoximines in good to excellent yields. The solid-state structure of a representative product was characterized by X-ray crystallography. Utilizing these reagents in synthesis provides a new, transition-metal-free approach towards N-alkynylated sulfoximines.

Copper-catalyzed oxidative cross-coupling of sulfoximines and alkynes

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.
