Potassium Persulfate Mediated Oxidative Radical Cyclization of 1,3-Dicarbonyl Compounds with Styrenes for the Synthesis of Dihydrofurans

A potassium persulfate promoted tandem radical addition/cyclization of 1,3-dicarbonyl compounds with styrenes has been developed. This transition-metal-free procedure provides an efficient approach to a diverse set of substituted dihydrofurans in moderate to good yields.
