Ketoreductases from Klebsiella pneumoniae (NBRC 3319) selectively reduce several 2-substituted ethyl 3-oxobutyrates to yield the corresponding syn-β-hydroxy esters with remarkable stereocontrol (de > 99 %, ee > 99 %). The enantiopure hydroxy oxo esters were synthetically manipulated to access new small-ring carbocycles.
来自肺炎克雷伯菌 (NBRC 3319) 的酮还原酶选择性地还原几种 2-取代的 3-氧代丁酸乙酯,以产生具有显着立体控制的相应顺-β-羟基酯(de > 99 %,ee > 99 %)。对映体纯羟基氧代酯被合成操纵以获得新的小环碳环。
