Abstract

13C NMR has been particularly useful for the identification of these tricyclic molecules. In the case of 3, the 13C NMR spectrum exhibits seven peaks. Two of them (corresponding respectively to equivalent carbons 1 and 8 and 7 and 9) have an intensity of twice the others. These data are consistent only with structure 3. The proton decoupled 13C NMR spectrum of 5 shows six signals, three of them having an intensity of twice the three others. This would ...
