Abstract:The presented article studied the reactions to synthesize 4-dimethylamino-2′,4′- dihydroxychalcone. The routine method to prepare this chalcone is aldol condensation,which can happen in the catalysts of strong alkali(10% KOH),organic amine(piperidine),and acid(boric acid). We compared the performance of these three catalysts,and results show that piperidine is the best catalyst with yield of 56.5% . Also the reaction conditions of piperidine catalysis aldol condensation were optimized to fit mass preparation. |
Key words:4-dimethylamino-2′,4′-dihydroxychalcone;aldol condensation;piperidine |
