N2 - 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. Copyright © 1992 John Wiley & Sons, Ltd.
