A convenient and rapid synthesis of enantiopure α-hydroxy-β-lactams using microwave-induced organic reaction enhancement chemistry has been developed. Reactions in domestic microwave ovens, which are very convenient and economical for small scale work in research or teaching laboratories, can also be conducted on a preparative scale of 100–500g in simple beakers or flasks.

Diastereospecific glycosylation of racemic alcohols by reaction with suitable glycal derivatives in the presence of iodine provides easy access to both enantiomers as illustrated by the preparation of an optically pure alpha-hydroxy beta-lactam that is an intermediate for the semisynthesis of taxol.
