本文介绍了在PPA存在下，由B15C5和DB18C6同过量的二羧酸发生酰化作用，得到酮酸1a～e和3a～c。再把所得相应的酮酸1a～e和3a～c利用黄鸣龙法制得4'-(ω－羧基多亚甲基)苯并-15-冠-5(2a～e)和4',4''(5'')-二(ω-羧基多亚甲基)二苯并-18-冠-6(4a～c)等一系列ω-冠醚酮酸。

A series of ω-crown ether-substituted alkanoic acids, 4'- (carboxypolymethylene) benzo-15-ceown-5 (2a～e) and 4',4'' (5'') -di (carboxy polymethylene) dibenzo-18-crown-6 (4a～c) were prepared by Huang Min-Lon method from the corresponding ketonic acids 1a～e and 3a～c, which were obtained by the acylation of B15C5 and DB18C6 with excess dicarboxylic acids in the presence of PPA.

Key words: ACYLATION, HUANG MINLON REACTION, KETONE ACID, CROWN ETHER
