  酸催化乙酰丙酸与 1,2 和 1,3-二醇的竞争性酯化和缩酮化：多相和均相催化剂的影响

  摘要：

  研究了乙酰丙酸 (LA) 与 1,2-乙二醇 (1,2-ED)、1,2-丙二醇 (1,2-PD) 和 1,3-丙二醇 (1,3-PD) 的缩合反应在 Dean-Stark 条件下，在苯中使用 Amberlyst-15 和对甲苯磺酸催化剂。在 Amberlyst-15 催化反应中，产物是缩酮和缩酮酯，而对甲苯磺酸催化反应生成酯和缩酮酯作为产物。在对甲苯磺酸催化的 1,2-ED 和 1,3-PD 反应中，LA 单酯产物在 180 分钟后作为主要产物形成，产率分别为 75% 和 97%。与之前报道的乙酰丙酸乙酯与二醇的酸催化缩酮化不同，LA 与二醇的缩酮化-酯化反应是一个复杂的过程。
