Bicyclononane-2,4-dione and 7-endo-benzyloxy-9-methylenebicyclononane-2,4-dione were prepared starting from bicyclononan-2-one and 7-endo-benzyloxybicyclononane-2,9-dione, respectively.The key reaction was the NCS oxidation of the 2,2-ethylenedioxy-4-phenylthiobicyclononanes, derived from the corresponding bicyclonon-3-en-2-ones.
Homoconjugation and transannular orbital interactions detected by photoelectron and13C-NMR spectroscopy. Bicyclo[3.3.1]nona-3,7-diene-2,6-dione and bicyclo[3.3.1]nonane-2,6-dione

Transannular orbital interactions between two ketone carbonyl groups located at positions 2 and 6 on the bicyclo[3.3.1]nonane carbocyclic framework were detected by 13C-NMR and photoelectron spectroscopy (PES). Thus, an ~4.4-ppm shielding of th
