Ceric ammonium nitrate-mediated oxidative cycloaddition of 1,3-dicarbonyls to conjugated compounds afforded substituted dihydrofurans, dihydrofurocoumarins, dihydrofuroquinolinones, and dihydrofurophenalenones in moderate yields. This new synthetic method has been applied to the synthesis of furonaphthoquinone natural products. (C) 2000 Elsevier Science Ltd. All rights reserved.
