Further examples of the use of 1-piperidyl esters for the synthesis of protected dipeptides have given good yields of pure product except when two valine residues were involved (in which case the reaction of the analogous p-nitrophenyl ester was also very slow), or when one residue was α-aminoisobutyric acid. The reactions of benzyloxy-carbonylamino-acid 1-piperidyl esters with the methyl esters of
