Abstract： Using substituted salicylaldehyde and diethyl malonate as raw materials，the basic hydrolysis reaction of esters was carried out after the synthesis of ethyl 3-carboxylate-coumarin derivatives，and the reaction intermediate 3-carboxylic acid-coumarin derivative was obtained by acidification.On this basis， bean derivatives were catalyzed and activated by a carboxylic acid acylation catalyst，and a series of acylation substitutions were carried out to obtain 26 target compounds， and the antibacterial activities of the target compounds were determined.The results showed that some target compounds had good antibacterial activity.
