A series of 2,3-disubstituted-5-oxochromeno[2,3-b]pyridine derivatives were synthesized under ultrasound irradiation, and also under conventional methods, from the reaction of 3cyanochromones with some active methylene compounds in the presence of a stoichiometric base. The structures of the products were unambiguously elucidated by 1D and 2D NMR experiments. Full assignment of all H and C NMR chemical

A new series of chromeno[2,3-b]pyridines was efficiently synthesized via chemical transformations of 6-methylchromone-3-carbonitrile with some methylene-active compounds bearing –CH2–CN and –CH2–CO– moieties. Some heteroannelated chromeno[2,3-b]pyridines were also synthesized. The structures of the new synthesized products were deduced on the basis of their analytical and spectral data.
