S-phenyl-S-pyridyl-sulfoximine 、 N,N-二乙基氯乙胺 以there is obtained, in a yield of 46% of theory, N-(2-diethylaminoethyl)-S-phenyl-S-(3-pyridyl)-sulphoximide的产率得到N-(2-diethylaminoethyl)-S-phenyl-S-(3-pyridyl)-sulphoximide
A novel and efficient method for the synthesis of N-S substituted sulfoximines has been established with h-BN-supported copper(II) nanomaterial as the catalyst. Catalyzed by this heterogeneous catalyst, the desired products were obtained with wide scope of substrates, good to excellent yields, free ligand and low-toxicity solvent. Moreover, after being reused ten times, there is almost no significant loss of its catalytic activity.

A versatile method for the synthesis of enantioenriched N–H sulfoximines is reported. The approach stems from the organomagnesium-mediated ring opening of novel cyclic sulfonimidate templates. The reactions proceed in high yield and with excellent stereofidelity with alkyl, aryl, and heteroaryl Grignard reagents. The chiral auxiliary is readily removed from the resultant sulfoximines via an unusual
