Abstract
The regioselective and chemoselective hydrolysis of an .alpha.-ester group of an amino acid diester using pig liver esterase enzyme (PLE) is disclosed. The amino acid diesters may be either N-protected or unprotected and the diester groups may be the same or different. In particular, the preparation of a number of .gamma.-ester glutamates and .beta.-ester aspartates are provided.
