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
