NMR Spectrum
Prediction： The signal observed at 65.84 was assignable to H-5, which corresponding carbon signal was displayed at 693.9 on the 13C-. NMR spectrum. The signal that appeared at 5172.2 was assignable to the carbonyl moiety of the lactone group at C-12. The signal that appeared at 5105.6 was due to the quartenary carbon C-4 activated by two geminal oxygen atoms. The peak observed at 579.7 was due to the quartenary carbon C-6 connected to an oxygen atom.
