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.
The title compound, C 10 H 17 NO 6 , was prepared by carrying out three S N 2 displacements on a branched sugar derivative, one of which was not planned. Its crystal structure was determined to con®rm the identity and stereochemistry of the product.
Single-crystal X-ray study T = 190 K Mean '(C±C) = 0.002 A Ê R factor = 0.031 wR factor = 0.078 Data-to-parameter ratio = 12.0 For details of how these key indicators were automatically derived from the article, see http://journals.iucr.org/e.
The relative configuration of the title compound, C~9~H~14~NO~5~, formed by catalytic hydrogenation of an azidolactone, has been established by X-ray crystallographic analysis. The absolute configuration was determined by the use of 2,3-__O__-isopropylidene-L-lyxono-1,4-lactone as the carbohydrate s
