For the molecular modelling calculations the force field TRIPOS was used as implemented in Sybyl 7.3 (Tripos Inc.). The starting structure was built with a ring puckering corresponding to a skewed boat conformation, as it was the only ring conformation in qualitative agreement with the experimental J-couplings, and, at the same time, showing the largest number of bulky exocyclic groups in the most stable equatorial or isoclinal orientations. The exocyclic torsions were optimized by determining the energy minimum in torsional energy maps with 60° increments (gridsearch module in Sybyl). Gasteiger-Hückel atomic partial charges were used and the energy minimization steps in all the calculations consisted in 1000 conjugated-gradients maximum iterations, an energy gradient limit of 0.01 Kcal/mol A, using a distance-dependent dielectric constant of 1·r, and a non-bonded cutoff of 8 A. Energy minimization led to significantly improved agreement between experimental and theoretical J-couplings. Theoretical distances were measured on the energy minimum, and the J-couplings were obtained using the Haasnoot-Altona empirical equation (Haasnoot, C. A. G.; De Leeuw, F. A. A. M.; Altona, C. Tetrahedron 1980, 36, 2783-2792). Any molecular model with an inverted configuration at C-2 was unable to predict the set of exclusive NOEs described in the discussion of results.
