    • 4. Removal of solvent in vacuo gave a residue which was purified by column chromatography (silica gel, 8:1 n-hex/AcOEt) to give 4b as a mixture of diastereomers (105 mg, 89%, 80% d.e.). Diastereomeric excess was determined by HPLC [DAICEL CHIRALCEL OD, hexane:iPrOH=95:5, flow rate: 2.0 mL/min, retention time: 4.1 min (minor) and 7.2 min (major)].
