具有光学活性的3-环己烯-1-羧酸是存在于多种药物中的重要结构单元。以易获取的1,2,3,6-四氢邻苯二甲酸酐为原料,通过猪肝酯酶催化的去对称化反应与光驱动加氢脱羧反应的组合,发展了一种具有高对映体选择性制备3-环己烯-1-羧酸的催化合成。实验与理论计算研究揭示了吖啶类光敏剂9-位的空间位阻与4-环己烯-1,6-二甲酸单甲酯加氢脱羧效果之间的关联。

Optically active 3-cyclohexen-1-carboxylic acid is a prevalent structural unit in various pharmaceuticals. Herein, by utilizing porcine liver esterase-catalyzed desymmetrization and light-driven hydrodecarboxylation, an unpresented catalytic asymmetric method for obtaining enantioenriched 3-cyclohexen-1-carboxylic acid from readily available 1,2,3,6-tetrahydrophthalic anhydride was developed. Through experimental and computational investigations, the correlation between the steric hindrance at the 9-position of the acridine photosensitizer and the effect of hydrodecarboxylation of 4-cyclohexene-1,6-dimethanoic acid monomethyl ester was revealed.

Key words: acridine photosensitizer, hydrodecarboxylation, porcine liver esterase
