(S)-(E)-(+)-1-Bromo-1-octene-3-ol was prepared in 85% yield and high optical purity (e.e. 97.4%) via a stereospecific reduction of corresponding bromo vinyl ketone using alcohol dehydrogenase from baker's yeast (EC 1.1.1.1) and NAD(P)H immobilized on Nucleosil 120-5 C18, and converted to 13(S)-hydroxy-9Z,11E-octadecadienoic (coriolic) acid.
(S)-(E)-(+)-1-溴-1-辛烯-3-醇以85%的收率和高光学纯度(ee 97.4%)制备,方法是使用醇脱氢酶将相应的溴乙烯基酮立体定向还原。面包酵母(EC 1.1.1.1)和NAD(P)H固定在Nucleosil 120-5 C 18上,并转化为13(S)-羟基-9Z,11E-十八碳二烯酸(coriolic)酸。
