Abstract

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