Abstract: The phosphine-catalyzed tandem annulation of allenylic alcohols with 1,1-dicyanoalkenes has been developed, giving various bicyclic tetrahydrocyclopentafuran derivatives in 40-89% yields with moderate to excellent diastereoselectivities. The fused ring was furnished through a sequential (3 +… read more here.
