| Abstract: | Anhydrous zinc chloride catalysed reactions of arylideneacetophenones 2a and 2c-e give 2, 4-diaryl-5-oxo-5,6,7,8-tetrahydro-2-chromens 4a-d with 1,3-cyclohexanedione respectively. Under similar conditions arylideneacetophenones 2b, 2d and 2f react with 5,5-dimethyl-1,3-cyclohexanedione (dimedone) to yield 7,7-dimethyl-2,4-diaryl-5-oxo-5,6,7,8-tetrahydro-2-chromens 4e-g. |
