cycloalkane-containing primary alcohols with vinyl acetate was performed and allowed the isolation of enantiopure alcohols. Lipases from P. cepacia, C. rugosa, C. antarctica, P. fluorescens, C. cylindracea and M. miehei exhibited remarkable activity towards acetylation of these alcohols, affording the corresponding acetates with high conversion. Due to the high lipase activity toward primary alcohols, the enantioselectivity
用乙酸乙烯酯对含苯并稠合的环烷烃的伯醇进行脂肪酶催化的对映选择性乙酰化,并分离出对映纯的醇。洋葱,南美白对虾,南极南美白对虾,萤光假单胞菌,圆柱状对虾和小黑背对虾的脂肪酶对这些醇的乙酰化显示出显着的活性,从而提供了具有高转化率的相应乙酸酯。由于对伯醇的高脂肪酶活性,对映选择性低。为了解决这个问题,采用对映体互补脂肪酶进行顺序动力学拆分,得到对映体纯的伯醇。该方法代表了一种获得带有环体系的手性结构单元的新方法,例如茚满,苯并二氢吡喃和四氢萘。
