5-Chloro-4-[(thiazolidin-5-ylidene)methyl]pyrrole-3-carboxylates and carboxylic acids: synthesis, recycling, and antimicrobial activity
摘要
5-Chloro-4-formylpyrrole-3-carboxylates and carboxylic acids can smoothly interact with thiazolidin-4-ones and form 5-chloro-4-[(thiazolidin-5-ylidene)methyl]pyrrole-3-carboxylates and carboxylic acids, respectively, which can further be transformed into thieno-[2,3-b]pyrrole-2,4-dicarboxylic acids through the alkaline hydrolysis. Moderate antimicrobial activity has been registered in 5-chloro-4-[(thiazolidin-5-ylidene)methyl]pyrrole-3-carboxylates and the corresponding carboxylic acids.
