Synthesis of novel flavonoid derivatives as potential HIV-integrase inhibitors

Eighteen novel flavonoid derivatives - substituted chalcones and flavones were synthesized and characterized by using NMR, IR, UV/Vis spectroscopy and elemental analysis. The target compounds were achieved by using a sequence of simple and effective reactions starting from phloroglucinol. The initial hydroxyl groups were protected by methylation and in the final flavones the 5-OH group was selectively demethylated by means of AlBr3. 5-methoxy flavones exhibit a strong fluorescence, which was quenched after the removal of the methyl group.
