摘要：

3-Arylaminomethylidenechroman-2-carboxamide has been synthesized by a one-pot three component reaction among 3-formylchromone, aromatic amine, and cyclohexyl isocyanide. 3-(N-alkylsubstitued/unsubstituted)aminomethylidenechroman-2-carboxamides were synthesized by heating Passerini products derived from chromone-3-carbaldehyde with different aliphatic primary amines. The products obtained from the reactions of aliphatic primary amines readily form chromeno[2,3-c]pyrrole when heated in acetic acid. Bischromanones have also been synthesized using this methodology.
