Abstract Seven daunorubicin analogs containing α- l -, α- d -, and β- d -glycosidic linkages, in which the natural occurring sugar ( l -daunosamine) was replaced by diastereo-isomeric 3-amino-2,3,6-trideoxyhexoses (3-epi- l -daunosamine, d -acosamine, d -daunosamine, d -ristosamine, and 3-epi- d -daunosamine), were prepared. In all cases, glycosidation with daunomycinone was performed in the presence
摘要七个具有α-l-,α-d-和β-d-糖苷键的柔红霉素类似物,其中天然存在的糖(l-柔红胺)被非对映异构体3-氨基-2,3,6-取代制备了三脱氧己糖(3-表-1-柔胺,d-花生胺,d-柔胺,d-ristosamine和3-ep-柔环胺)。在所有情况下,都在存在对甲苯磺酸的情况下,从1-O-乙酰基-2,3,6-三苯氧基-4-O-对硝基苯甲酰基-3-三氟乙酰胺基吡喃葡萄糖(由相应的甲基3-氨基-2,3,6-三苯氧基己吡喃糖苷)或由1,5-脱水-2,3,6-三苯氧基-4-O-对硝基苯甲酰基-3-三氟乙酰胺基己糖-1-烯醇(由糖或假糖,3-氨基通过叠氮化钠取代并随后还原而引入)。
