Chiral (salen)manganese(IlI) complexes 1 catalyzed the asymmetric clesymmetrization of Nprotected meso-pyrrolidine derivatives 3, 6-8, 15 and 18 by enantiotopic selective C-H oxidation in the presence of term~aal oxidant iodo~ylbenzene. The oxidation occurred chemoselectively at the carbon ct to the

## Abstract Catalytic properties of a series of chiral (pyrrolidine salen)Mn(III) complexes for asymmetric oxidation of aryl methyl sulfides were evaluated. Moderate activity, good chemical selectivity and low enantioselectivity were attained with iodosylbenzene as a terminal oxidant. Enantioselect
