The most relevant NOE correlations were those between 3-H and both the methyl group at C-7 and the hydrogen atom trans to the methyl group (Ht). NOE contacts were also observed between 2a-H and both Ht and the methyl group at C-7, as well as between the last two proton signals and the axial methyl group at C-4.

This energy calculation was very sensitive to the force field used. Amber force field calculation on 1b gave a population of 70% of conformer A leading to major aldehyde stereoisomer 1d, while with MM2 calculation, the stability of the conformers was reversed, since only 30% of conformer A was present in the equilibrium at the reaction temperature

2 group of the ethyl ester of the nitrile derivative 2d appeared as a clear quadruplet pattern, indicating that there is no restriction on the rotation of this fragment. This is in contrast to what was observed for compounds 1d, 1e and 3d with axial carboxylate groups that show nonequivalence of their methylene ester protons.
