The title compound was isolated by several recrystallisations from a 1:l mixture of diastereomers which was obtained in 75% yield from the reaction of 1,2:3,4-di-O-isopropylidene-c~-D-galactopyranose with epichlorohydrin. The absolute configuration of this isomer (30% yield) was established by X-ray
