---Reaction of N-alkyl, N-aryl, and N-H sulfoximines with m-chloroperbenzoic acid cleanly gives the corresponding sulfones in high yield. In the case of the cleavage of N-alkyl and N-arylsulfoximines, formation of the corresponding nitroso compounds as the other reaction product was proven. Starting from enantio- and diastereopure sulfoximines, a number of chiral sulfones, including the axially chiral sulfone 6 and the sulfonyl-functionalized homoallylic alcohol 8, have been prepared. Reaction of the enantiopure sulfoximine 30 with Merrifield resin gave the polymer-bound sulfoximine 32. Oxidative cleavage of 32 afforded the sulfone 16 in high yield. Deprotonation of the sulfoximine resin 32 and reaction of Li-32 with benzaldehyde and propanal furnished the β-hydroxysulfoximine resins 33a and 33b, respectively. Oxidative cleavage of 33a and 33b readily afforded the β-hydroxy sulfones 14a and 14b, respectively.
