Gas chromatographic separation of the enantiomers of 5-alkanolides (alkano-δ-lactones) without conversion was attempted in a capillary column coated with a liquid phase containing heptakis (2,3,6-tri-O-methyl)-β-cyclodextrin (CD column) ; however, separation was difficult, especially in the case of lactones with a high carbon number. Therefore, conversion by a simple process using popular chemicals was tried. It was found that 2-methoxy-6-alkyl-tetrahydropyrans (alkano-δ-lactol methyl ethers) were good derivatives for enantiomeric separation of the lactones in the CD column. The δ-lactones were converted to δ-lactol methyl ethers in one step by using sodium borohydride and methanol in the presence of aluminum chloride and water. This conversion method is applicable for enantiomeric separation of the lactones from hexano- to octadecano-δ-lactone.
