Eco-friendly synthesis of fused pyrano[2,3-b]pyransviaammonium acetate-mediated formal oxa-[3 + 3]cycloaddition of 4H-chromene-3-carbaldehydes and cyclic 1,3-dicarbonyl compounds
Various substituted polycyclic pyrano[2,3-b]pyrans were synthesizedviathe condensation of 4H-chromene-3-carbaldehydes and their areno-condensed analogues with hetero- and carbocyclic 1,3-dicarbonyl compounds in acetic acid. Ammonium acetate was used as a green catalyst for the reaction. The process...
