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.
提供了一种制备光学活性的Formula I的2-(acyloxymethyl)-1,3-oxathiolanes的方法,包括制备外消旋化合物和酶催化的对映体动力学分辨。该发明还可以进一步提供对酶促反应的副产物进行酯化和外消旋化的方法。通过这种方式,制备出2(R)-(benzoyloxymethyl)-1,3-oxathiolane,作为制备抗HIV药物Apricitabine的有用中间体。
