ABSTRACT:
The invention constitutes an enzymatic method for resolution of a racemic mixture of hydroxy compounds. A D,L mixture of the hydroxy compound is phosphorylated to form the D,L monoorthophosphate esters of the hydroxy compound. Thereafter, the D,L mixture of phosphorylated compounds is treated with a stereospecific phosphatase, such as wheat germ acid phosphatase, which causes the hydrolysis of substantially only one optical isomer of the monoorthophosphate ester. The resulting hydrolyzed isomer of the hydroxy compound is then separated from the remaining monoorthophosphate ester.
