A suitable intermediate for the synthesis of eremophilanes and bakkanes was prepared by a highly regioselective and stereoselective one-step synthesis through a niobium catalyzed Diels-Alder reaction. As a demonstration of the versatility of this intermed

(equation presented) Treatment of α-alkylidenelactones 3a-d with Bu3SnH and a catalytic amount of Et3B effected a 5-exo radical cyclization preferentially to provide the corresponding 1 and 2 in a ratio of 70:30 to 100:0. Meanwhile,
