There is provided a process for manufacture of optically-active, 2-(acyloxymethyl)-1,3-oxathiolanes of Formula I comprising a preparation of a racemic compound and an enzyme-catalyzed kinetic resolution of the enantiomers. The invention may further provide for the esterification and racemization of the by-product of the enzymatic reaction. In this manner, 2(R)-(benzoyloxymethyl)-1,3-oxathiolane is prepared as a useful intermediate for manufacture of the anti-HIV drug Apricitabine.
