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
