Capsaicin is the important ingredient of hot chili pepper which is studied for pain relief, weight reduction, cardiovascular related diseases, and etc. We have prepared 7 capsaicin analogues by amide coupling reaction with EDC and HOBt. In particular, 4 analogues of them were obtained through ester coupling besides amide coupling at the same time. There were no product through only ester coupling. The more simple carboxylic acid were obtained the higher yield in ester coupling.

Fischer esterification is known to have no selectivity. However, we confirmed that monoesters of saturated dicarboxylic was obtained in general Fischer esterification condition. We were trying to react to the six saturated dicarboxylic acids in the same reaction condition, and the yields of a single esterification product were approximately 14∼26%.
