Notes:
The determination of 3J(13C,1H) for two sets of diastereoisomeric norbornene-derived lactones was achieved by using fully coupled 13C spectra or the SINEPT-2D method. The stereochemical elucidation of these compounds was performed by using long-range carbo-proton couplings, combined in some cases with NOE techniques and heteronuclear 2D correlations. Torsional angle dependence and the influence of γ-substitution in the 13C-α - C-β - C-gM-1H fragment on 3J(13C,1H) values were verified in these cases.
