采用常规酯化方法合成吲哚丁酸甲酯和乙酯，然后用吲哚丁酸甲酯与长链和支链的醇在对甲苯磺酸或钛酸四丁酯的催化下进行酯交换，合成了七种吲哚丁酸酯。它们的分子结构用红外光谱、核磁共振和元素分析进行了确认，并测定七种吲哚丁酸酯的生物活性。 The methyl ester and ethyl ester of indole butyric acid were synthesized by the conventional esterification method and then the transesterification was carried out with the methyl indole butyrate and long chain and branched chain alcohols under the catalysis of p-toluenesulfonic acid or tetrabutyl titanate, Seven indole butylates were synthesized. Their molecular structure was confirmed by infrared spectroscopy, nuclear magnetic resonance and elemental analysis, and the biological activities of seven indole butyric esters were determined.
