A second crystalline diacetonide, the title compound, C 13 H 20 O 7 , has been isolated from the sequential treatment of d-tagatose with aqueous sodium cyanide, followed by acetone in the presence of acid. Structural ambiguities with regard to the size of both the lactone and ketal rings are resolve

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
