✦ Synopsis
The ring size of both the lactone and the ketal protecting group in the title compound, C 9 H 14 O 5 , have been established by X-ray crystallographic analysis. The crystal structure consists of hydrogen-bonded spirals parallel to the b axis.

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
The title compound, C~26~H~31~F~3~O~8~SSi, provides a unique example of the crystal structure of an organic trifluoromethanesulfonate attached to a primary C atom. The absolute configuration is determined by the use of D-ribose as the starting material.
