摘要：

In contrast to porcine pancreatic lipase (PPL), the serine proteases aP 41 and thermitase are suited as catalysts for the enantioselective ester hydrolysis of methyl (+/-)-2,3-O-isopropylideneglycerate (rac-1). These enzymes allow the preparation of methyl (S)-(-)-2,3-O-isopropylideneglycerate (1) with an enantiomeric excess of 84-87% in a yield of 19-27% related to the starting racemate.
