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

X-ray crystallographic analysis firmly establishes the ribo stereochemistry and the unusual boat conformation of the title branched carbon chain lactone, C 9 H 13 N 3 O 4 , arising from an unexpected rearrangement in the nucleophilic substitution of a trifluoromethanesulfonate. There are two molecul
