Enantioselective hydrolyses of 2-chloroacetates derived from racemic 1,1,1-trifluoro-2-alkanols were found to proceed very smoothly in the presence of a catalytic amount of lipase MY to yield the corresponding (R)-alcohols with high optical purity. In this procedure, Purification was easily carried out only by a simple distillation of the reaction mixture, enabling us to extend this reaction in a larger scale.

水解反应进行得非常顺利,生成的相应(R)-醇具有很高的光学纯度。在这一过程中,只需对反应混合物进行简单的蒸馏就可以轻松地进行提纯,这使我们能够将这一反应扩大到更大规模。
