Abstract
A procedure for the preparation of optically active (2R,5S)- and (2S,5 S)-2-Carboxy-1,4-diaza-[4.3.0]bicyclononane is described. The method i s based on the reduction of diketopiperazines obtained from cyclizatio n of Pro-L-Ser or Pro-D-Ser and occurs without loss of enantiomeric pu rity. The synthesis is based on readily available starting materials a nd can be easily arranged for multigram scale preparations. Copyright (C) 1996 Elsevier Science Ltd
