Construction of Dispiro-Indenone Scaffolds via Domino Cycloaddition Reactions of α,β-Unsaturated Aldimines with 2-Arylidene-1,3-indenediones and 2,2′-(Arylmethylene)bis(1,3-indenediones)
[Image: see text] The catalyst-free domino reaction of α,β-unsaturated N-alkyl or N-arylaldimines with two molecules of 2-arylidene-1,3-indanediones in dry acetonitrile resulted in polysubstituted spiro[indene-2,3′-indeno[2′,1′:5,6]pyrano[2,3-b]pyridines] in moderate to good yields and with high dia...
