All <jats:sup>1</jats:sup>H and <jats:sup>13</jats:sup>C signals were identified unequivocally. Vicinal <jats:sup>1</jats:sup>H‐<jats:sup>1</jats:sup>H coupling constants. NOESY experiments and iodine substituent effects on the <jats:sup>13</jats:sup>C chemical shifts show that these molecules prefer the chair conformation.</jats:p>
