    疏水性酯在含有一元醇的水溶液中形成疏水性稳定的相遇复合物的动力学证据
    摘要:
    四种酯的 pH 无关水解,对甲氧基苯基 2,2-二氯乙酸酯 (1a)、对甲氧基苯基 2,2-二氯丙酸酯 (1b)、对甲氧基苯基 2,2-二氯丁酸酯 (1c) 和对甲氧基苯基 2 , 2-二氯戊酸酯 (1d) 在稀水溶液中已被研究作为添加的共溶乙醇、1-丙醇和 1-丁醇的摩尔浓度的函数。中性水解的速率常数随着共溶质浓度的增加而降低。这些动力学介质效应对酯的疏水性和一元醇的疏水性都有响应。使用热力学和动力学模型分析观察到的速率效应。动力学模型表明疏水稳定的遭遇复合物的分子图,平衡常数 K(ec) 通常小于 1,其中共溶质阻断水解酯的反应中心以防止水的侵袭。根据热力学模型,这些相遇复合物的形成导致主要的初始状态稳定化。这些水解反应的表观焓和活化熵的降低对应于不利的焓和有利的络合熵,这证实了遇到的复合物通过疏水相互作用而稳定。

    synthesis of not only racemic decursivine and serotobenine, but also enantiopure (+)‐ and ()‐decursivine and a variety of their analogues. The present syntheses represent the shortest pathway for the total synthesis of decursivine and serotobenine to date. Moreover, the newly developed cascade sequence for the total synthesis of decursivine does not need any protecting steps. The scope and the reaction
