Abstract

The anodic oxidation of (±)‐1,2‐O‐isopropylideneglycerol at a silver/silver oxide electrode with a controlled potential of +0.9 V vs. SCE in 2.5 N sodium hydroxide affords sodium (±)‐2,3‐O‐isopropylideneglycerate in a yield of 75%. Treatment of this salt with dimethyl sulfate and potassium carbonate in boiling acetone leads to methyl (±)‐2,3‐O‐isopropylideneglycerate in a yield of 81%.

## Abstract 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 (π)‐2,3‐__O__‐isopropyl‐ideneglycerate (__rac__‐1). These enzymes allow the preparation of methyl (__S__)‐(−)‐2,3‐__O__‐i
