Dynamic kinetic asymmetric transformation (DYKAT) of a series of 1,5-diols has been performed in the presence of Candida antarctica lipase B (CALB), Pseudomonas cepacia lipase II (PS-C II), and ruthenium catalyst 4. The resulting optically pure 1,5-diacetates are useful synthetic intermediates, which was demonstrated by the syntheses of both an enantiopure 2,6-disubstituted piperidine and an enantiopure
在南极假丝酵母脂肪酶B(CALB),洋葱假单胞菌脂肪酶II(PS-C II)和钌催化剂4的存在下,进行了一系列1,5-二醇的动态动力学不对称转化(DYKAT)。纯的1,5-二乙酸酯是有用的合成中间体,这通过对映纯2,6-二取代哌啶和对映纯3,5-二取代吗啉的合成得到证明。
