Ceric(IV) ammonium nitrate-mediated oxidative cycloaddition of 1,3-dicarbonyls to vinylsulfides afforded substituted dihydrofurans with sulfide groups in moderate yields. This new synthetic method has been applied to thesynthesis of benzo[b]naphtho[2,3-d]furan-6,11-dione and furanoflavone natural products such as millettocalyxins C and pongol methyl ether.
