base-assisted boronic acid catalysis for the dehydrative self-condensation of carboxylic acids is described. Arylboronic acid bearing bulky (N,N-dialkylamino)methyl groups at the 2,6-positions can catalyze the intramolecular dehydrative condensation of di- and tetracarboxylic acids. This is the first successful method for the catalytic dehydrative self-condensation of carboxylic acids.
描述了布朗斯台德碱辅助硼酸催化羧酸的脱水自缩合反应。在2,6-位带有大的(N,N-二烷基氨基)甲基的芳基硼酸可以催化二羧酸和四羧酸的分子内脱水缩合。这是羧酸催化脱水自缩合的第一个成功方法。
