  由醇与碳酸二甲酯轻松进行碱辅助合成不对称碳酸酯

  摘要：

  摘要描述了一种简单且方便的碱介导的由醇与碳酸二甲酯合成不对称碳酸酯的方法。该反应受到所用碱的强度的显着影响，并且发现叔丁醇钾是该反应的最佳促进剂。几乎在所有情况下，反应都是选择性的，并以优异的收率（80-90％）提供了相应的不对称碳酸甲酯。 图形概要

  We have successfully developed an easy and efficient bioprocess for asymmetric organic carbonate synthesis by performing Novozym 435 mediated esterification of DMC and alcohols in this work. Under the optimized conditions (60 °C, molar ratio of alcohol to DMC 1 : 12), the highest yield of carbonate can reach 95.6%. An additional advantage of the new process is the fact that 90% of the original activity of the enzyme is retained after being recycled nine times. Consequently it has potential as a useful enzyme-catalyzed process for the industrial production of asymmetric organic carbonates.

  我们成功开发了一种简单高效的生物过程，通过在本工作中进行Novozym 435介导的DMC和醇的酯化反应，实现了不对称有机碳酸酯的合成。在优化条件下（60°C，醇与DMC的摩尔比为1:12），碳酸酯的最高产率可达到95.6%。新工艺的另一个优点是，酶在经过九次回收后仍保留90%的原始活性。因此，它有潜力成为工业生产不对称有机碳酸酯的有效酶催化工艺。
