1,1,1-trifluoro-2-phenylbut-3-yn-1-yl acetate（1，1，1-三氟-2-苯基丁-3-炔-1-醇乙酸酯）应该有误，不可能1-C上连5个基团（C为五价了），应该为：1,1,1-trifluoro-2-phenylbut-3-yn-2-yl acetate（1，1，1-三氟-2-苯基丁-3-炔-2-醇乙酸酯）。一篇相关文献如下：

Identification of a metagenome-derived esterase with high enantioselectivity in the kinetic resolution of arylaliphatic tertiary alcohols

Abstract

35 metagenome-derived esterases bearing a GGG(A)X motif were screened for activity and enantioselectivity in the hydrolysis of a range of tertiary alcohol acetates. Most of the active esterases showed little or no enantioselectivity in the hydrolysis of the terpinyl acetate, linalyl acetate and 3-methylpent-1-yn-3-yl acetate. However, one esterase showed excellent enantioselectivity (E > 100) in the kinetic resolution of 1,1,1-trifluoro-2-phenylbut-3-yn-2-yl acetate as confirmed by a preparative scale reaction.
