The oxidoreductases Lactobacillus brevis alcohol dehydrogenase (LBADH) and Candida parapsilosis carbonyl reductase (CPCR) are suitable catalysts for the reduction of ketones to afford enantiopure sec. alcohols. A broad variety of alkynones (1, 3, and 5) are accepted as substrates and the corresponding propargylic alcohols (2, 4, and 6) are obtained in good yield and excellent enantiomeric excess. By
氧化还原酶短乳杆菌醇脱氢酶 (LBADH) 和近平滑念珠菌羰基还原酶 (CPCR) 是还原酮以提供对映体纯 sec 的合适催化剂。醇类。广泛的炔酮(1、3 和 5)可用作底物,并以良好的产率和优异的对映体过量获得相应的炔丙醇(2、4 和 6)。通过改变取代基的空间需求,可以调整 ee 值,甚至可以改变产品的构型。
