and -2,4-dideoxy-β-d-xylo-hexopyranose hydrochlorides (21) were prepared from the corresponding azido derivatives. 1H-and 13C-n.m.r. spectra of 15, 18, 21, and of 2-amino-1,6-anhydro-2,4-dideoxy-β-d-lyxo-hexopyranose hydrochloride in D2O were compared with those of the corresponding deoxy derivatives and other related compounds. Isomerization of 2-amino-1,6:3,4-dianhydro-2-deoxy-β-d-altropyranose into
1,6-脱水-d-甘露糖胺的部分苄氧羰基化,随后的甲磺酰化和用甲醇钠处理,得到1,6:3,4-二脱水-2-苄氧羰基氨基-2-脱氧-β-d-阿糖基吡喃糖(9)。用碘化钾在9中将环氧乙烷环裂解,乙酰化并用三丁基锡烷进行脱卤作用,得到4-O-乙酰基-1,6-脱水-2-苄氧基羰基氨基-2,3-二脱氧-β-d-阿拉伯糖基-六吡喃糖(13) 。通过脱乙酰基和氢解除去13中的保护基,得到标题化合物(15)的盐酸盐。由相应的叠氮基制备了2-氨基-1,6-脱水-2,3-二脱氧-β-d-核糖(18)和-2,4-二脱氧-β-d-二甲苯基-吡喃葡萄糖酸盐(21)。衍生品。15、18、21和2-氨基-1,6-脱水2的1H和13C-nmr光谱,将D2O中的4-dideoxy-β-d-lyxo-hexopyranose盐酸盐与相应的脱氧衍生物和其他相关化合物进行了比较。还研究了将2-氨基-1,6:3,4-二脱水-2-脱氧-β-d-阿托拉那糖异构化为2
