Abstract:

The present work was devoted to be used as an efficient green technique for synthesis of novel, dihydropyrazolo[1,5-a] pyrimidine (3, 5), [1,2,4]triazolo[1,5-a]pyrimidine (7) and 3,4-dihydrobenzo[4,5]imidazo[1,2-a]pyrimidine (9) derivatives incorporating Schiff base moiety. The reactions of chalcone 1 with different heterocyclic amines were achieved under solventless conditions using microwave irradiation and/or under classical reflux condition. In general, microwave irradiation offered the advantages of high yields, short reaction times, and simplicity compared to the conventional methods. The structures of all the compounds were confirmed by analytical and spectral data. Some of the synthesized compounds were evaluated against HepG-2 and showed significant antitumor activities.
