Synthesis of 3-aminomethylidenechroman-2-carboxamides by a Sequential One-pot Three Component Reaction and by Post-Passerini Condensation Modification

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.

Indium triflate: A new catalyst for (4 + 2)-cycloaddition of chromone Schiff's bases

Indium triflate was introduced as a new catalyst for (4+2)-cycloaddition of chromone Schiff's bases. 3,4-Dihydro-2H-pyran reacted with a variety of chromone Schiff's bases in the presence of indium and scandium triflates at ambient temperature and pressur
