Abstract

The study of preparation by classic and microwave irradiation methods, spectroscopic characterization of 3-Acyl-2-R-methylchromone derivatives(R = H, C6H5, ArO ). Some subsequent reactions of these products with hydroxylamine and by aldol condensation with 3-formylchromones have been studied.
