Abstract
A simple and convenient synthesis of a novel series of pyrido[1,2- a ]benzimidazoles was efficiently achieved from the condensation reactions of 1 H -benzimidazol-2-ylacetonitrile ( 1 ) with some 3-substituted chromones, chromone-3-carboxylic acids, chromone-3-carboxamides, ethyl chromone-3-carboxylates and chromone-3-carbonitriles. Reaction of compound 1 with 2-aminochromone-3-carboxaldehydes produced 2-amino-3-(1 H -benzimidazol-2-yl)chromeno[2,3- b ]pyridines. The reaction mechanisms and spectral data were also discussed.
