General description

马来酸二甲酯是一种二烯亲和物，可用作合成二烯、塑料和共聚物的化学中间体。

马来酸二甲酯 (DMM) 是一种具有反应活性的二烯亲和物，可与取代呋喃进行超声波辅助Diels-Alder 反应。研究人员已经报道过，DMM 可通过介孔硅SBA-15-负载 Cu催化的气相氢解来合成1，4-丁二醇。据报道氯化铝可以加速DMM 和蒽的Diels-Alder反应。DMM 可通过马来酸酐、硫酸和甲醇的酯化反应合成。

Application

  • 通过与2,3-二甲基马来酸酐的可逆缩合实现的牛6S 羧肽酶原A的解离：亚基III部分表征的应用：该研究探索了采用2,3-二甲基马来酸酐实现牛6S 羧肽酶原A的解离，重点介绍了其在酶亚基部分表征中的应用。该研究显示了二甲基马来酯衍生物在蛋白质化学和酶结构研究中的潜力。（Puigserver and Desnuelle, 1975）。

Based on (1)H NMR studies, subtle electronic factors rather than pre-organisation dictate the binding stoichiometry of the new, norbornene based, anion hosts 1 and 2 with acetate, however, the binding of dihydrogenphosphate appears to be based solely on steric constraints.

Diels–Alder Reaction

The Diels–Alder reaction is the reaction between a conjugated diene and an alkene (dienophile) to form unsaturated six-membered rings. It is also referred to as a cycloaddition.
