摘要

A procedure for the preparation of optically active (2R, 5S)-and (2S, 5S)-2-Carboxy-1, 4- diaza-[4.3. 0] bicyclononane is described. The method is based on the reduction of diketopiperazines obtained from cyclization of Pro-L-Ser or Pro-D-Ser and occurs without loss of enantiomeric purity. The synthesis is based on readily available starting materials and can be easily arranged for multigram scale preparations.
