efficient method for the solvolysis of sterically hindered esters under high pressure is described. Transesterification is carried out in the presence of DBU at room temperature and at a pressure of 10 kbar to give quantitative conversions within short reaction times. The substrates examined included aromatic and aliphatic esters of sterically hindered alcohols and phenols. An optically pure benzyl ester
描述了在高压下溶剂解位阻酯的温和,快速和有效的方法。酯交换反应是在DBU存在下于室温和10 kbar压力下进行的,以在较短的反应时间内给出定量转化率。检查的底物包括空间受阻醇和酚的芳族和脂族酯。选择光学纯的苯丙氨酸苄酯来研究氨基酸酯在高压反应条件下的外消旋作用。
