We describe a modular synthesis of cyclic and acyclic 1,5-P,N-phosphino-sulfoximines by using a phospha-Michael reaction of the corresponding alkenyl sulfoximines with HPPh2/KOtBu as key step, which proceeds with medium diastereoselectivity. Th

The molecular ions of S-(1-alkenyl)-N-sulfoximides 1 are transformed into the N-(phenylsulfenyl)sulfonamides 3+. by a 1,2-migration of the alkenyl group to the O-atom of the sulfoximide function followed by a 2,3-sigmatropic
STEREOSELECTIVE SYNTHESIS OF ENANTIOMERICALLY PURE 1-(E)-ALKENYLSULFOXIMINES

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.
