The intramolecular cyclopropanation reactions of the aromatic ring in tetrahydronaphthyl diazomethyl ketones initiated by rhodium(II) and copper(II) derived transition metal catalysts afford stable norcaradiene products. Further elaboration has led to pentacyclic structures that have considerable potential for the expeditious synthesis of complex polycyclic diterpenes.

The ketones 9, 27, and 51 were prepared by modified or novel routes.The analogous tosylhydrazones 10, 28, and 52 were photolyzed in 0.5 N NaOH to generate the carbocations 15, 34, and 53, respectively, by way of diazonium precursors. 2,3-Unsaturati
