...-Methylbutan-1-ol [( R )-1] was isolated from the mixture by column chromatography and the enantiomeric purity was measured by gas chromatography on a β-Dex225 chiral stationary phase column (ee >98%). ( R )-1 was then treated with triflic anhydride and pyridine to form ( R )-(+)-2-methylbutan-1-yl triflate...
