(Acyloxy)alkyl esters are commonly employed as prodrugs of carboxylic acid containing compounds. Several optically active (acyloxy)alkyl esters are prepared from a coupling and rearrangement reaction between optically active O-acyl-α-hydroxy acids and 3-chloroperoxybenzoic acid mediated by diisopropylcarbodiimide. The effect of temperature and solvent on the reaction is discussed. An application of
(酰氧基)烷基酯通常用作含羧酸化合物的前药。通过由二异丙基碳二亚胺介导的旋光O-酰基-α-羟基酸和3-氯过氧苯甲酸之间的偶联和重排反应,可以制备几种旋光(酰氧基)烷基酯。讨论了温度和溶剂对反应的影响。描述了该反应在制备布洛芬前药形式中的应用。
