    • Chiral HPLC study carried out using a Chiralcel-OD column eluting with a 95 hexanes-5% propan-2-ol solvent mixture at 0.6 ml/min. A racemic sample of the target under study was prepared and investigated prior to the enantiomerically enriched product. Retention times: major enantiomer=18.9 min, minor=22.2 min

    • In all cases, the major (cis-) diastereoisomers display a large diaxial coupling of ca. 12 Hz between the C-2 proton at the chiral centre created on electrophile-induced cyclisation and the axial C-3 proton. For the minor (trans-) diastereoisomers, the now equatorial C-2 proton displays a much weaker axial-equatorial coupling (ca. 4 Hz) to the same C-3 proton

    • Chiral HPLC study carried out using a Chiralcel-OD column eluting with a 99.5 hexanes-0.5% propan-2-ol solvent mixture at 0.25 ml/min. A racemic sample of the target under study was prepared and investigated prior to the enantiomerically enriched product. Retention times: 6a: major enantiomer=46.9 min, minor=42.5 min; 7a: major enantiomer=51.2 min, minor=60.1 min
