The lipase B from Candida antarctica (Novozym 435®, CALB) efficiently catalyzed the kinetic resolution of some aliphatic secondary alcohols: (±)-4-methylpentan-2-ol (1), (±)-5-methylhexan-2-ol (3), (±)-octan-2-ol (4), (±)-heptan-3-ol (5) and (±)-oct-1-en-3-ol (6). The lipase showed excellent enantioselectivities in the transesterifications of racemic aliphatic secondary alcohols producing the enantiopure
来自南极念珠菌 (Novozym 435®, CALB) 的脂肪酶 B 有效催化了一些脂肪族仲醇的动力学拆分:(±)-4-methylpentan-2-ol (1), (±)-5-methylhexan-2-ol (3)、(±)-octan-2-ol (4)、(±)-heptan-3-ol (5) 和 (±)-oct-1-en-3-ol (6)。脂肪酶在外消旋脂肪族仲醇的酯交换中显示出优异的对映选择性,以良好的产率生产对映纯醇(> 99% ee)和乙酸酯(> 99% ee)。使用 CALB 脂肪酶,在简单的条件下,乙酸乙烯酯作为酰化剂,己烷作为非极性溶剂,成功地实现了外消旋醇的动力学拆分。
