| Abstract: | Exocyclic nitrones smoothly participate in intramolecular cycloaddition reactions to provide bridged and fused polycarbocycles. The exploitation of this methodology in the total syntheses of the sesquiterpenes (±)-7,12-secoishwaran-12-ol (44), (±)-hirsutene (56), (±)-coriolin (68) is also presented. |
