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.
该发明涉及一种用于分离羟基化合物的外消旋混合物的酶法。将羟基化合物的D,L混合物磷酸化,形成羟基化合物的D,L单正磷酸酯。然后,将D,L磷酸化化合物混合物与立体特异性的磷酸酶(例如小麦胚芽酸磷酸酶)处理,这会导致单正磷酸酯的一个光学异构体的水解。然后将水解后的羟基化合物的异构体与其余的单正磷酸酯分离。
