Various phenols, methoxy aromatic compounds, 3- and 4-hydroxycoumarins and enols smoothly condense with 2-hydroxy-2,2′-biindan-1,1′,3,3′- tetrone 1 in an acid medium producing 2-aryl/alkyl-2,2′-biindan-1, 1′,3,3′-tetrones in high yields. The adducts of re
Facile Regioselective Synthesis of 3-amino-2-(2-arylindanedionyl) indenones from 2-aryl-2,2-biindan-1,1,3,3 -tetrones and Solvent-Dependent Keto-Enol Tautomerism in Enaminones

Refluxing 2-Aryl-2,2-biindan-1,1,3,3-tetrones in acetic acid with urea produces 3-amino-2-(2-arylindanedionyl)indenones regioselectively within 2-3 h. in good yields. X-ray crystal structures of the products clearly indicate that in the solid state the co
