The asymmetric oxidation of aryl methyl sulfides to sulfoxides with hydroperoxides has been achieved using catalytic amounts of the complex formed in situ between Ti(i-PrO)4, (S,S)-diphenylethan- 1,2-diol 1 and water. The sulfoxides are obtained in 60% yield and 67-80% enantiomeric excess.

Abstract

The asymmetric oxidation of aryl methyl sulfides to sulfoxides with hydroperoxides has been achieved using catalytic amounts of the complex formed in situ between Ti(i-PrO)4, (S,S)-diphenylethan- 1,2-diol 1 and water. The sulfoxides are obtained in 60% yield and 67-80% enantiomeric excess.
