Abstract

The syntheses and additions of allylsilanes, and-stannanes to enones and dienones forming spiro-and fused-bicyclic products are described. The stereoselectivity observed is dependent on the Lewis acid used. The tin terminator reverses the stereoselectivities in the bicyclo [4.3. 0] nonanone cases.
