    • Theoretical coupling constants were calculated over the minimized structures for both diastereomers, by using the Karplus-Altona equation implemented in the Macromodel 7.0 program. The calculations were performed with an MMFF force field, using high-quality parameters, and repeated with an AMBER force field. Similar results were obtained in both cases
