Optically active (E)-N-tosyl-S-(1-alkenyl)-S-phenylsulfoximines 4 are synthesized stereoselectively in a one pot sequence from readily available 1 via C-silylation, metallation and reaction of the corresponding lithiosulfoximine 3 with various carbonyl compounds.The E1-MS spectra of the so prepared alkenylsulfoximines 4 show unexpected fragmentations, pointing to a new, unusual S-O-migration of the 1-alkenyl moiety.
