摘要：
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-oxocyclohexanecarboxylates. The structures of the reaction products were confirmed by H-1 and C-13 NMR spectroscopy and by X-ray diffraction analysis.
