N2  - The synthesis of heptacyclo [7.7.0.02,6.03,15.04,12.05,10.011,16]hexadeca-7,13- diene (9) is described. The diene (9) was obtained in three steps from the known diketone  heptacyclo -[6.6.0.02,6.03,13.04,11.05,9.010,14] tetradecane - 7,12-dione (5). Double ring expansion of (5) (with diazomethane) gave (12). Conversion of (12) into-the bis ( tosylhydrazone ), followed by double Bamford -Stevens rearrangement, gave the diene (9).
