(Chemical Equation Presented) Enticing structures: The formal syntheses of 1 and 2 were accomplished by using a cascade strategy involving an enyne cycloisomerization reaction and an intramolecular Diels-Alder reaction starting from 3. The resulting 4 underwent a late-stage ring contraction to enable the preparation of a reported advanced intermediate, thereby constituting a formal synthesis of the structurally intriguing title compounds.
