An expedient synthesis of coumarin-pyridone conjugate molecules 2a-o is reported via one-pot reaction between (E)-3-(3-arylacryloyl)-2H-chromen-2-ones 1a-o, ethyl 2-nitroacetate and ammonium acetate. The structures of synthesized compounds have been unambiguously confirmed by spectroscopic analyses (NMR, IR and MS). All the compounds were screened for their anti-microbial activities against three Gram-positive bacterial strains, two Gram-negative bacterial strains and four fungal organisms. Compounds 2d, 2i, 2k, 2oexhibited mild anti-bacterial activity and 2d, 2m were found to be moderately active against all the tested fungal organisms. Compound 2k showed good inhibitory potential against the tested yeasts organisms.

GO has been found as a remarkable heterogeneous carbocatalyst for the solvent-free synthesis of 2-(substituted benzoyl)-3-(substituted phenyl)imidazo[1,2-a]pyridines from chalcones and 2-aminopyridine. The present methodology offers a novel and eco-friendly approach with appreciable yields of the desired products.
