Very High Diastereofacial Selectivity in the Nucleophilic Epoxidation of N-(p-Tolylsulphonyl)vinylsulphoximines

Bailey, Peter L.,Clegg, William,Jackson, Richard F. W.,Meth-Cohn, Otto

, p. 200 - 202 (2007/10/02)

Nucleophilic epoxidation of N-(p-tolylsulphonyl)vinylsulphoximines (6) using lithium t-butylhydroperoxide proceeds with very high diastereofacial selectivity, the sense of which was established by a single crystal X-ray structure determination, to give N-
