Kinetic resolutions of (±)-3-chloro-3-arylpropanols by lipase mediated acetylation are described for the first time. Acetylation with CCL provided the best enantioselectivity amongst the enzymes used. Enantiomerically enriched products were obtained with up to 78% ee after two successive lipase-catalyzed acetylations. Different substituents on the aromatic ring and bromide, instead of chloride, on
首次描述了通过脂肪酶介导的乙酰化作用的(±)-3-氯-3-芳基丙醇的动力学拆分。在使用的酶中,用CCL乙酰化可提供最佳的对映选择性。在两次连续的脂肪酶催化的乙酰化反应后,获得的对映体富集产物的ee最高可达78%。发现在底物上的芳环和溴上的不同取代基,而不是氯,对反应的对映选择性没有剧烈的影响。
