The proposed stereochemistry was deduced from the value of the ¹H NMR coupling constants, which showed a cis relationship 2-H/3-Ha/4-H and a trans relationship 2-H/3-Hb and 4-H/3-Hb (J 3a = 6.6, 6.9 Hz, while J 3b = 3.8, 4.4 Hz).

The experimental coupling constants matched theoretical coupling constants, which were calculated over minimized structures by using the Karplus-Altona equation implemented in the Macromodel 7.0 program. The calculations were performed with a MMFF force field, using high-quality parameters.

Representation using ChemDraw 3D 8.0 (CambridgeSoft),
which agrees with calculations performed with Macromodel 7.0. The aldehyde 20 adopts a similar conformation. - 10b For the formation of related
