Enantiomerically pure, stable 4-(methoxycarbonyl)phenyl 2,4,6-tri-isopropylphenyl selenoxide (-)-3 was isolated by fractional recrystallization of diastereomeric 4-phenyl 2,4,6-tri-isopropylphenyl selenoxide dia.-(1) followed by removal of the chiral source.The absolute configuration around the selenium atom was determined by X-ray crystallographic analysis of diastereomerically pure selenoxide (-)Se-(1).

Fractional recrystallization of diastereomeric 2,4,6-triisopropylphenyl 4'-(l-menthyloxycarbonyl)phenyl selenoxide gave optically pure (-)-selenoxide.Transesterification of this diastereomerically pure (-)-selenoxide with methanol gave enantiomeric (-)-2,4,6-triisopropylphenyl 4'-(methoxycarbonyl)-phenyl selenoxide in 88.1percent optical purity.
