The construction of multiply fused carbocyclic systems has long commanded the attention of synthetic organic chemists. One need only trace the lengthy history associated with the production of steroids and steroid-like compounds to realize the veracity of such a statement. The primary ring-forming methodologies that have emerged as a consequence of the steroid efforts consist of (a) Friedel-Crafts type acylation reactions,(b) the Dieckmann ...
