The optical resolution of (±)-2,2,2-trifluoro-1-(1-pyrenyl)ethanol was achieved by using lipases. In particular, Pseudomonas aeruginosa lipase (lipase LIP) showed high enantioselectivity (E = > 100) and reactivity in the alcoholysis of the chloroacetyl ester of the title compound. The reactivity of the lipase LIP-catalyzed enantioselective alcoholysis of the chloroacetate with 1-hexanol was much higher than that of the acetylating the alcohol with vinyl acetate.
利用脂肪酶实现了(±)-2,2,2-三氟-1-(1-芘基)乙醇的光学解析。尤其是铜绿假单胞菌脂肪酶(脂肪酶 LIP)在醇解标题化合物的氯乙酰酯时表现出很高的对映选择性(E = > 100)和反应活性。脂肪酶 LIP 催化的对映体选择性醇解氯乙酸酯与 1-己醇的反应活性远高于醇与乙酸乙烯酯乙酰化的反应活性。
