A series of flavonol derivatives were synthesized according to Algar-Flym-Oyamada reactions and chalcone were was synthesis according to the Claisen-Schmidt reactions. Chalcones were prepared by condensing equimolar of o-hydroxy acetophenones with 6-methoxynapthadehyde in alcoholic alkaline medium at room temperature. The resultant chalcones were immediately reacted with H2O2 in the presence of a mixture of aqeous alcoholic alkali to obtained corresponding flavonol. All the syntesized flavonol were characterized by means of their, IR, ¹HNMR, Mass spectral data, elemental analysis and their physical properties. All flavonol were tested for their anfifungal and antibacterial activity. All the sysntesized flavonol exhibited moderate to good antimicrobial activity.
