摘要

In the preceeding paper we reported that aziridines 1 could be deprotonated and functionalized in a stereoselective way. 1 However, the obtention of each diastereomer required a chromatographic separation which proved to be tedious on a multigram scale. We therefore decided to investigate the ester cleavage of such species under kinetic resolution, which could lead to a diastereomerically pure water-soluble aziridino acid on the one hand, and its epimeric ester on the other ...
