    摘要:
    CO2 的简单交换 羧酸中的二氧化碳 (CO2) 损失是生化和合成环境中的常见反应,但它通常涉及催化或长时间加热。孔等人。现在报告某些极性溶剂,如二甲基甲酰胺,它们本身会促进可逆的 CO2 损失,这些都是由一个碳桥接到芳环的羧酸盐。由于环上有吸电子取代基,即使在室温下,同位素标记的 CO2 也可以有效交换。或者,与醛的反应导致醇的形成。科学,这个问题 p。557 某些极性溶剂在令人惊讶的温和条件下使结合在苄基位点的 CO2 变得不稳定。有机化学中的许多经典和新兴方法依赖于二氧化碳 (CO2) 挤出来生成用于成键事件的反应中间体。涉及微观逆向的合成反应 - 反应中间体的羧化 - 通常使用非常不同的条件进行。我们报告化学稳定的 C(sp3) 羧酸盐,如芳基乙酸和丙二酸半酯,在二甲基甲酰胺溶液中经历未催化的可逆脱羧。脱羧 - 羧化发生在底物上,在其他条件相同的情况下,对布朗斯台德酸的原脱羧作用有

    公开(公告)日:1994-01-11
    A process for obtaining a substantially pure enantiomer of an aryl-substituted aliphatic carboxylic acid is described. The process utilizes first an enantiomerically enriched mixture the of aryl-substituted aliphatic carboxylic acid obtained from kinetic resolution, diastereomeric crystallization or asymmetric synthesis processes. This enriched mixture is reacted with a base producing a salt that has the following properties: 1) has at least one eutectic point; 2) a composition that is not at the eutectic point; and 3) a eutectic composition that is closer to the racemic composition than is the eutectic composition of said aryl-substituted carboxylic acid. Substantially pure, enantiomeric salt is separated, leaving a mother liquor comprising the solvent and aryl-substituted aliphatic carboxylic acid enriched in the other enantiomer.
