A method for producing a hydroxy-amino ester, or derivative thereof, is provided. A substituted β-ketodiester having a ketone group and two ester functional groups is contacted with a ketoreductase under conditions permitting the reduction of the ketone group to an alcohol. Only one of the ester functional groups is regioselectively hydrolyzed to the corresponding carboxylic acid, whereby a non-hydrolyzed ester functional group remains. The carboxylic acid is converted to an amine or a derivative thereof to produce a hydroxy-amino ester or derivative thereof. A number of novel hydroxy-amino esters are prepared by the method.
提供了一种制备羟基-氨基酯或其衍生物的方法。将具有酮基和两个酯基官能团的取代β-酮二酯与酮还原酶接触,并在条件允许的情况下将酮基还原为醇。仅对其中一个酯基官能团进行区域选择性水解成相应的羧酸,从而保留了一个未水解的酯基官能团。将羧酸转化为胺或其衍生物,以产生羟基-氨基酯或其衍生物。通过该方法制备了许多新型羟基-氨基酯。
