摘　　要：　　Oxidative addition of carbon-centred radicals to alkenes mediated by metal salts ( MnⅢ, CeⅣ, HgⅡ,PdⅣ, AgⅠ,and CuⅡ) has received considerable attention over last decade in organic synthesis for construction of carbon-carbon bond. [1,2] Among them, manganese(Ⅲ) acetate and ceric(Ⅳ) ammonium nitrate (CAN) have been use most efficiently. Recently, CAN-mediated oxidative cycloaddition of 1,3-dicarbonyl compounds to alkenes, conjugated compounds, enol silyl ethers and alkynes, has been studied extensively. We exploited that the CAN-mediated oxidative cycloaddition of 1,3-dicarbonyl compounds to β-aryl-α,β-unsaturated ketones afforded dihydrofuran derivatives in moderate yields. All the products were characterized by 1H NMR, 13C NMR, MS and HRMS spectra.……
