The relative configuration at C-2 of 2,4-dimethyl-3,4-__O__-isopropylidene-L-arabinono lactone, C~10~H~16~O~5~, which exists in the boat form, was unequivocally established by X-ray crystallographic analysis. The absolute configuration was determined by the use of 2-__C__-methyl-D-ribonolactone as a
The relative stereochemistry of the fluoro substituent (as __ribo__) and the ring size of the lactone (as five) in the title compound, C~6~H~9~FO~4~, have been established by X-ray crystallographic analysis.
