Organo-catalyzed aldol condensation of 2-hydroxyacetophenone and 4-nitrobenzaldehyde underwent regio- and enantioselective cyclization via intramolecular 5-exo-trigonal cyclization to give 4-nitroaryl-3-benzofuranones. The product formation indicated that

Piperidine - mediated reactions of 2-acylphenols and 4-nitrobenzaldehydes afforded 3-benzofuranones in high yield (82-95%) at reflux temperature in ethanol. The electron density calculation of HOMO-LUMO energy in the chalcone intermediates by DFT showed t
