Abstract

Isopropylidene diphenylsulfurane and isopropylidene triphenylphosphorane react by the same (Re) face of the alkylidene malonate derived from the acetonide of (d)-glyceraldehyde to produce almost exclusively a single diastereoisomer of the corresponding dimethyl cyclopropane-1,1-dicarboxylate.
