An attempt was made to synthesise newer 3-methylflavones with various substitution on the ring A and B of 2-phenylchromen-4-one. They were evaluated for antioxidant activity and antibacterial activity against the Gram-positive and Gram-negative bacteria. Five test compounds exhibited DPPH radical scavenging activity with IC50 below 100 mu g/ml, and the same test compounds exhibited 50-100% growth inhibition in Gram-positive bacteria against standard Amoxicillin.

Although deprotonation of electron-poor C–H bonds to carbon anions with bases has long been known and widely used in organic synthesis, the hydride elimination from electron-rich C–H bonds to carbon cations or partial carbocations for the introduction of nucleophiles is a comparatively less explored area. Here we report that the carbonyl β-C(sp3)–H bond hydrogens of ortho-acyl phenols could be substituted
