Asymmetric oxidation of sulfides is one of current topics and many useful methodologies for this purpose have been mported to date.13) Some of these methodologies are well known to be also useful for the epexidation of olefins. However, differing from epoxidation, there is no good methodology for ca
A6structz Asymmetric oxidation of sulfkles was examined by using (salen)mangane&III) complexes as catalysrp and (8S,8'S,l"S,2"S)-complex (2b) was found to show high asymmetric induction up to 90% ee. Its diastercom \* (8R.8'R.l"S.2"S)-complex (la) that showed excellent asymmetric induction in the ep
