Diastereospecific glycosylation of racemic alcohols by reaction with s
uitable glycal derivatives in the presence of iodine provides easy acc
ess to both enantiomers as illustrated by the preparation of an optica
lly pure alpha-hydroxy beta-lactam that is an intermediate for the sem
isynthesis of taxol.
