(S)- and (R)-2-Hydroxyhex-5-enoic acid and (S)- and (R)-2-hydroxyhept-6-enoic acid were prepared in excellent yields and enantiomeric excesses (>99% ee) from the corresponding α-keto esters by the enzyme catalysed hydrolysis of the ester and reduction of the ketone in a single pot process. The enantioselective synthesis of (S)-2-hydroxypent-4-enoic acid was achieved via reaction of the reagent derived
(S)和(R)-2-羟基己5-烯酸以及(S)-和(R)-2-羟基庚6-烯酸以优异的收率和对映体过量(> 99%ee)制备酶催化酯的水解并在单锅法中还原酮,从而生成相应的α-酮酯。(S)-2-羟基戊-4-烯酸的对映选择性合成是通过使烯丙基溴和铟金属衍生的试剂与水合草酸8-苯基薄荷基乙二酸酯的水合物反应而实现的。
