ABSTRACT

Chalcones are 1,3-diphenyl-2-propene-1-one, in which two aromatic rings are linked by a three carbon -unsaturated carbonyl system. Pyrimidines are one of the important heterocyclic compounds with various biological activites. In this view, it was proposed to synthesize some novel pyrimidines from chalcones. Chalcones are prepared by treating 4-imidazole-1-yl-acetophenone with different aromatic aldehydes. These chalcones on condensation with guanidine HCl and KOH gave 4-(4-(1H –imidazole-l-yl)-pyrimidin-2-amine derivatives. They have been screened for their antibacterial activity against Gram positive bacteria B.subtillis & B.pumilus and gram negative bacteria E.coli & P.vulgaris and antifungal activity against A.niger & P.crysogenium.

Keywords: Chalcones, pyramidines, 4- imidazole-1-yl-acetophenone, 4-(4-(1H –imidazole-l-yl)-pyrimidin-2-amine.
