The Horner-Wadsworth-Emmons reaction of N-benzyloxycarbonyl(dimethoxyphosphinyl) glycine esters withs-symmetric prochiral 4-substituted-cyclohexanones under basic conditions is described. This reaction gives unusual α,β-didehydroamino acids with a chiral axis in their racemic form. The methodology has been extended to the synthesis of dipeptides containing a phenylalanine residue and these unusual new α,β-didehydroamino acids at the i+2 position.
