Enantiomerically pure glycerol derivatives, e.g. S-1,2-O-isopropylidene, S-1,2-O-benzylidene, and R-1,2-O-dibenzyl glycerol, have been prepared from 1,2R-O-protected erythritols in high yields. The latter compounds are easily obtained from erythorbic acid and are useful building blocks in the synthesis of a host of optically active compounds having biological activity.
