| 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. |
