Abstract

Epoxidation of 1-tolylthio-1-nitroalkenes containing an allylic Boc-protected amino group yields cis-oxazolidmones 13, formed by intramolecular trapping of the presumed intermediate epoxides by the carbamate group. Epoxidation of the analogous Z- or Fmoc-protected derivatives yields the corresponding syn-epoxides which, although they cannot be isolated, can be trapped with aqueous ammonia, or more efficiently benzylamine, to give stereoisomerically pure anti-alpha,beta-diamino acid derivatives.
