Chiral gas chromatography of diol 10 was performed on a CE Instruments Trace GC (Thermoquest) machine with an SGE Cydex-β stationary phase (25 m x 0.22 mm) with helium as the carrier gas and a flow rate of 1.5 mL per min using a FID detector. An isocratic temperature of 40 °C was followed for 120 minutes, followed by a temperature ramp of 4 °C to 140 °C for 120 minutes and comparison with an authentic racemic sample. Retention times were 159.25 min (S) and 159.87 min (R).

Chiral gas chromatography of the bis-trifluoroacetate derivative of 17 was performed on a CE Instruments Trace GC (Thermoquest) machine with an SGE Cydex-β stationary phase (25 m x 0.22 mm) with helium as the carrier gas and a flow rate of 2 mL per min using a FID detector. An isocratic temperature of 50 °C was followed for 120 minutes, followed by a temperature ramp of 4 °C to 110 °C for 60 minutes and comparison with an authentic racemic sample. Retention times were 139.38 min (S) and 139.89 min (R).

Although chromatographic purification led to the separation of diol and auxiliary, the isolated yield of the diol could be increased by acetylation of the crude reaction mixture resulting from reduction, which facilitated chromatographic purification of the bis-acetate derivative of the diol.
