Treatment of nitroso Diels-Alder cycloadducts 1 with diazomethane in the presence of palladium acetate gives synthetically useful exo-6-oxa-7-azatricyclo[,4]octane derivatives 7 in good to excellent yield. Using this methodology, a conformationally restricted 2',3'-methano carbocyclic nucleoside was efficiently synthesized from nitroso cycloadduct 1a in 7 steps.
