Abstract Direct condensation of carboxylic acids and alcohols with electronic, steric, and functional group variations was carried out using the environmentally benign, moisture-stable, inexpensive, and recoverable iron(III) acetylacetonate [Fe(acac)3] as catalyst (5 mol%). This iron salt efficiently catalyzed the esterification of several primary and secondary alcohols in refluxing xylene, without the need
摘要 使用环境友好、耐湿、廉价且可回收的乙酰丙酮铁 (III) [Fe(acac)3] 作为催化剂 (5 mol) 进行具有电子、空间和官能团变化的羧酸和醇的直接缩合反应。 %)。这种铁盐有效地催化了回流二甲苯中几种伯醇和仲醇的酯化反应,而无需脱水试剂。通过用苯甲酸对外消旋 1-苯基乙烷-1,2-二醇中的伯醇官能团进行选择性酯化,证明了所提议方案的化学选择性。酯化也适用于未掩蔽的 α-羟基酸、guasaromatic、杂环和 N-保护的氨基酸。补充材料可用于本文。去出版商' 的 Synthetic Communications® 在线版以查看免费的补充文件。图形概要
