    • 3. Refinement in an orthorhombic space group provided no solution while refinement in the triclinic space group P1 led to a conventional R of 0.917 with the same problems for the disordered array of the annellated six- and five-membered C rings. Further details of the structure investigation are available from the Fachinformationszentrum Karlsruhe, D-76344 Eggenstein-Leopoldshafen (Germany), on quoting the depository number CSD-59287, the names of the authors, and the journal citation.

    • We could show that treatment of 13 with nBuLi gives 16 as one of the major products of a very complex mixture. The cyclization of 13 to 16 can be rationalized as follows. (Chemical Equation Presented)

    • 2 at -78°C. The assumption is supported by the fact, that the amount of naphthodihydrodiphosphete 17 did not increase by warming the NMR tube to -30°C.
