Article abstract of DOI:10.1016/S0040-4039(00)60838-9

A convenient asymmetric synthesis of both (3R)-and (3S)-piperazic acids has been developed that is based on electrophilic hydrazination of a chiral bromovaleryl carboximide enolate with di-tert-butyl azodicarboxylate, followed by subsequent intramolecular
