Hexopyranose crystal structure

The crystal structure of the hydrochloride and hydrobromide of isoquinocycline A was elucidated by the method of single, isomor-phous replacement.67 The glycosyl group, which constitutes about 20% of the molecule, is that of a branched-chain, eight-carbon sugar, namely, 2,6-dideoxy-4-(L-glycero-l-hydroxyethyl)-a-L-xylo-hexopyranose-IC (17).
