  An Efficient Synthesis of Derivatives of 2‐Acetamido‐4‐amino‐2,4,6‐trideoxy‐D‐galactopyranose

  摘要：

  Methyl 2-acetamido-4-amino-2,4,6-trideoxy-alpha-D-galactopyranoside (10) was synthesized from D-glucosamine hydrochloride in eight steps in an overall yield of 31%. Key steps include the selective benzoylation at O-3 of methyl 2-acetamido-2,6-dideoxy-alpha-D-glucopyranoside in 89% yield and the subsequent Mitsunobu reaction using diphenylphosphoryl azide as the azide source which proceeded in 92% yield. Di- and mono-benzyloxycarbonyl derivatives of 10 were also prepared.

  -glycoside was the starting material, the product was free N -acetyl- d -quinovosamine. The allyl 6-bromo-6-deoxy-α- and -β-glycosides, after partial benzoylation, were reduced by tributyltin hydride to allyl 2-acetamido-3- O -benzoyl-2,6-dideoxy-α- and -β- d -glucopyranoside. The α anomer was converted into allyl 2-acetamido-2,6-dideoxy-α- d -galactopyranoside (α glycoside of N -acetyl- d -fucosamine)

  摘要用三苯基膦和N-溴丁二酰亚胺处理2-乙酰氨基-2-脱氧-d-吡喃葡萄糖的糖苷，形成6-溴-6-脱氧衍生物。这些在钯催化剂存在下的氢解作用下，产生2-乙酰氨基-2,6-二脱氧-d-吡喃葡萄糖（N-乙酰基-d-喹啉胺）的糖苷。当苄基β-d-糖苷为起始原料时，产物为游离的N-乙酰基-d-喹啉胺。在部分苯甲酰化后，烯丙基6-溴-6-脱氧-α-和-β-糖苷被氢化三丁基锡还原为烯丙基2-乙酰氨基-3-O-苯甲酰基-2,6-二脱氧-α-和-β -d-吡喃葡萄糖苷。通过连续的三氟甲基磺酰化，苯甲酸铯置换和O-去苯甲酰化，将α端基异构体转化为烯丙基2-乙酰氨基-2,6-二脱氧-α-d-吡喃半乳糖苷（N-乙酰基-d-岩藻糖胺的α糖苷）。

  To understand the contradictory results on the structure of the lipopolysaccharide isolated from a Yersinia enterocolitica O:3, both anomers of methyl 2-acetamido-2,6-dideoxy-D-xylo-hexopyranosid-4-ulose were prepared. The key steps of the synthetic pathway were the selective acetylation of the methyl 2-acetamido-2,6-dideoxy-alpha,beta-D-glucopyranosides, the oxidation of the 4-position to form the keto-sugars, and deacetylation to provide the target compound. Surprisingly, the last step was accompanied by a disproportionation to give methyl 2-acetamido-2,6-dideoxy-alpha- and beta-D-glucopyranosides and N-(5-hydroxy-6-methyl-4-oxo-4H-pyran-3-yl)acetamide as side-products.
