| Abstract: | The reactions of 1-aryl-5,5-dichloropenta-2,4-dien-1-ones with ethyl acetoacetate in the presence of EtONa give ethyl 4-aryl-6-(2,2-dichlorovinyl)-4-hydroxy-2-oxocyclohexane-carboxylates.
The structures of the reaction products were confirmed by1H and13C NMR spectroscopy and by X-ray diffraction analysis.
