ethoxynaphthalen-1-yl)-6-bromonaphthalen-2-yloxy)butanoate was hydrolyzed by CAL-B to afford a corresponding acid with excellent enantioselectivity (E > 200). Two types of optically active binaphthol derivatives, 1-(2-hydroxy-6-(naphthalen-1-yl)naphthalen-1-yl)-6-(naphthalen-1-yl)naphthalen-2-ol and 6-butyl-1-(6-butyl-2-hydroxynaphthalen-1-yl)naphthalen-2-ol, were prepared by this chemo-enzymatic reaction
南极假丝酵母脂肪酶B(CAL-B)是有机合成中最常用的酶,用于制备旋光性醇。但是,尚未用于(±)-2,2'-联萘酚的光学拆分。我们建立了一种有效的针对2,2'-联萘酚衍生物的面向接头的设计,该设计适合使用CAL-B催化的水解反应进行光学拆分。用CAL-B水解4-(1-(6-溴-2-甲氧基甲氧基萘-1-基)-6-溴萘-2-基氧基)丁酸甲酯,得到具有优异对映选择性的相应酸(E> 200)。两种类型的光学活性联萘酚衍生物,1-(2-羟基-6-(萘-1-基)萘-1-基)-6-(萘-1-基)萘-2-醇和6-丁基-通过该化学酶促反应方案制备1-(6-丁基-2-羟基萘-1-基)萘-2-醇,并用作对称反应的手性模板。
