Costa, Marta published the artcileSelective synthesis of some imidazopyridine-fused chromones, Related Products of pyridine-derivatives, the publication is Tetrahedron (2011), 67(45), 8622-8627, database is CAplus.
A fused heterocyclic scaffold combining the imidazo[1,2-a]pyridine with a substituted chromone was synthesized in a one-pot procedure. The reaction proceeds by intramol. cyclization of 1-(2-imino-2H-chromen-3-yl)pyridinium chloride in ethanol and in the presence of DABCO. A detailed study of the exptl. conditions allowed a clear understanding of the reaction pathway.
