X-ray crystallographic analyses are reported for the two title compounds (8 and 9), of which the former crystallized in two modifications (8n and 8b). In all three structures, the pyranose rings have the %, (D) conformation and the substituents at C-l are axial and those at C-24-4 are equatorial. Th
