Abstract Two rare amino sugars, 3-acetamido-3-deoxy- and 4-acetamido-4-deoxy- d -altrose, were prepared from levoglucosenone (1,6-anhydro-3,4-dideoxy-β- d - glycero -hex-3-enopyranos-2-ulose) respectively by reduction of the carbonyl group, selective cis -oxyamination of the carbon-carbon double bond, detosylation of the p -toluenesulfonamido group, acetylation, acetolysis of the 1,6-anhydro bond,
摘要以左旋葡糖酮(1,6-脱水-3,4-二脱氧-β-d-甘油- hex-3-enopyranos-2-ulose)分别通过还原羰基,碳-碳双键的选择性顺式氧化,对甲苯磺酰胺基的去甲苯基化,乙酰化,1,6-脱水键的乙酰化,最终使O-乙酰基脱乙酰化。可以通过选择烯丙基羟基的保护基来控制通过还原左葡糖醛酮而获得的烯丙基醇的碳-碳双键的顺式氧化胺的区域选择性。
