Enzymatic synthesis of (S)-1,2-O-isopropylidene glycerol

This invention relates to a process for the synthesis of (S)-1,2-O-isopropylidene glycerol by hydrolysis of a racemic mixture of (R,S)-1,2-O-isopropylidene glycerol acetate catalysed by Kluyveromyces marxianus, recovery of unreacted (R)-1,2-O-isopropylidene glycerol acetate, and hydrolysis thereof
