Both enantiomers of a series of synthetically valuable 2-methylglycerol derivatives have been prepared with >99% ee using a chemoenzymatic reaction sequence. The introduction of chirality was achieved by enantioselective esterification of 1,2-O-protected 2-methylglycerol 3 or enantioselective hydrolysis of its butyryl ester 4. The enzymatic reaction proceeded with unusually high selectivity and velocity for a primary alcohol (ester) substrate.
