recyclable heterogeneous ionicliquid catalyst was synthesized. Catalytic activity of the CaO@SiO 2 @AIL hybrid nanoparticles was investigated for synthesis of the pharmaceutically valuable 2-imino-2 H- chromene and dihydropyrano[ c ]chromenederivatives. A wide range of amines and aromatic aldehydes containing either electron-withdrawing or electron-donating substituent were examined using optimized conditions
anthocyanins. A number of compounds with the chromene moiety are known as potential inhibitors of notum pectinacetylesterase, hMAO, aldose reductase, dihydrofolate reductase, TNFa, and acetylcholinesterase. Functionalized 2-iminochromenes have been a subject of increasing interest. A number of these compounds are used as protein tyrosine kinase (PTK) inhibitors, as well as anti-Alzheimer, antimicrobial, anticancer

Cyanoacetamide derivatives were reacted with salicylaldehyde under different conditions afforded chromenes and coumarin derivatives respectively. A number of chromeno[3,4-c]pyridinederivatives were prepared from the reaction of N-cyclohexyl-2-imino-2H-chromene-3-carboxamide with malononitrile and/or cynaothiocatemaide. Bischromeno[3,4-c]pyridinederivatives were prepared from the reaction of N,N’-(ethane-1
