Lipase B from Candida antarctica (CALB) has been selected as the most suitable enzyme to catalyze the regioselective monoacetylation of 1,5-diol isoprostane intermediate, using vinyl acetate as an acyl transfer reagent in THF. We next applied this reaction on linear 2-substituted, 2,2′-disubstituted-1,5-pentanediols, and cyclic 2,3-disubstituted-1,5-pentanediols. To rationalize the regioselectivity
已选择南极假丝酵母(CALB)的
脂肪酶B作为最合适的酶,使用
乙酸乙烯酯作为THF中的酰基转移试剂来催化1,5
-二醇异
前列腺素中间体的区域选择性单乙酰化。接下来,我们将该反应应用于直链的2-取代的2,2'-二取代的
1,5-戊二醇和环状的2,3-二取代的
1,5-戊二醇。为了使观察到的区域选择性合理化,进行了分子对接模拟。
