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 Robert Kourist, Sajja Hari Krishna, Jesal S. Patel, Flash Bartnek, Timothy S. Hitchman, David P. Weiner and Uwe T. Bornscheuer Org. Biomol. Chem., 2007, 5, 3310-3313 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.  |
