Limitations, mechanism and understanding of the origins of stereocontrol in (S)-dimethylsulfonium-(p-tolylsulfinyl)methylide-mediated epoxidation reactions
Midura, Wanda H.,Cypryk, Marek
experimental part, p. 177 - 186 (2010/04/29)
The reaction of the (S)-dimethylsulfonium-(p-tolylsulfinyl)methylide with aldehydes gave α,β-epoxy sulfoxides with high enantioselectivity and diastereoselectivity dependent on the aldehyde. The mechanism of the 'model' reactions [ylide substituted with M
(S)-dimethylsulfonium(p-tolylsulfinyl)methylide: A new chiral sulfonium ylide and its use in asymmetric epoxidation
Midura, Wanda H.
, p. 733 - 736 (2007/10/03)
The title optically active sulfonium ylide was prepared by methylation of easily available (-)-(S)-p-tolylmethylthiomethyl-sulfoxide and subsequent deprotonation. Its reaction with aldehydes gave α,β-epoxy sulfoxides with full enantioselectivity and moder
