4-benzoquionone and carboxylic acids provides a new and efficient method for the preparation of alkyl carboxylates from the corresponding alcohols under mild and neutral conditions. Further, the yields of the corresponding inverted carboxylates were equally high in the case of chiral secondary or tertiary alcohols.
一种使用原位形成的烷氧基二苯基膦(即二苯基次膦酸酯)、易得的 1,4-苯醌和羧酸的新型氧化还原缩合反应,为在温和和中性条件下从相应的醇制备羧酸烷基酯提供了一种新的有效方法使适应。此外,在手性仲醇或叔醇的情况下,相应的转化羧酸酯的产率同样高。
