A simple, efficient, and eco-friendly procedure has been developed for the synthesis of bis(4H-chromene-3-carbonitrile) derivatives using chitosan as catalyst under microwave-assisted reaction conditions. For the sake of comparison, the reaction was also carried out under conventional heating in the presence of each of chitosan and piperidine as basic catalysts.

An efficient and convenient method for the synthesis of bis(4H-chromene-3-carbonitrile) derivatives by one-pot, multicomponent reaction of bis-aldehydes, malononitrile, and dimedone in the presence of a catalytic amount of piperidine is reported. Bis(2-benzylidene-1H-indene)-1,3-(2H)-dione derivatives were obtained as the main products as a result of reaction of the bis(arylidenemalononitriles) with indandione. The anti-influenza H5N1 virus activities of the newly prepared bis-chromene derivatives are also investigated.
