Abstract
A compound of the formula A, wherein R* is a chiral auxiliary, and where the configuration at the asymmetric carbon atom between oxygen and sulfur is (R), (S), or combinations of (R) and (S), useful in the preparation of enantiomerically enriched 1,3-oxathiolane nucleoside analogues, for example (−)-FTC and 3TC.
