    Abstract A convenient one-pot multi-component strategy was conducted successfully under catalyst-free conditions employing water and PEG-400 as the efficient and cheap promoting medium. Three types and nearly 50 2-amino-3-cyano-4H-pyran annulated derivatives were synthesized in good to excellent yields by the condensation of a series of aromatic aldehydes with malononitrile and different 1,3-dicarbonyl

    Saccharose was applied as a green and natural catalyst for the one-pot, three-component condensation between aromatic aldehydes, malononitrile, and resorcinol, or 4-hydroxycoumarine to afford the corresponding pyran-annulated heterocyclic systems. This green methodology offers several advantages such as the use of a non-hazardous catalyst, easy access, clean work-up, excellent yields, short reaction time, and environmentally mild conditions. In addition, 1,8-dioxodecahydroacridine and 2-substituted benzimidazole derivatives have been synthesized from commercially available starting materials, arylaldehydes, dimedone, amines, or ammonium acetate and o-phenylenediamine using the mentioned catalyst.
