  A facile synthesis of the tetrasaccharide repeating unit of mannoglucan from Microellobosporia grisea

  摘要：

  A facile synthesis of the tetrasaccharide repeating unit of mannoglucan from Microellobosporia grisea was achieved through coupling of 4,6-O-benzylidene-1,2-O-ethylidene-alpha-D-glucopyranose with per-O-benzoylated mannopyranosyl trichloroacetimidate, followed by debenzylidenation, selective 6-O-mannopyranosylation, then hydrolysis of the 1,2-O-ethylidene group, 1,2-O-acetylation and conversion to the 1-trichloroacetimidate, and subsequent condensation of the activated trisaccharide with allyl 2,3,6-tri-0-benzoyl-alpha-D-glucopyranoside.

  使用新型炔型接头固相合成寡糖：通过 Sonogashira 反应选择载体上的反应位点

  摘要：

  精心设计了两种具有炔基甲氧基部分的新型炔烃型接头，用于寡糖的固相合成。通过炔丙基糖苷与聚合物负载的碘苯的 Sonogashira 反应形成糖残基和固体支持物之间的炔丙基糖苷型接头。炔丙酯型接头也通过4-(炔丙氧基羰基)苄基糖苷与后者的相同反应构建。两种接头对酸例如 TFA 都是稳定的，但在通过用 Co 2 (CO) 8 处理转化为相应的炔-钴络合物后，可以很容易地用这种酸裂解。后一种酯接头通常是有利的，因为温和裂解释放出产物作为其易于纯化的羧基苄基糖苷。

• Regioselective Benzoylation of 6-O-Protected and 4,6-O-Diprotected Hexopyranosides as Promoted by Chiral and Achiral Ditertiary 1,2-Diamines

  日期：2002.12

  Monobenzoylation of triols (6-O-silylated glycopyranosides) or diols (4,6-O-benzylidenated glycopyranosides) with benzoyl chloride and triethylamine at −60° to 23° is promoted by catalytic amounts of ditertiary 1,2-diamines. The regioselectivity depends mostly on the structure of the alcohols; it is modulated by the configuration and constitution of the diamines, as shown by comparing the effect of Oriyama's

  日期：——

  Two new alkyne-type linkers having alkynylmethyloxy moieties were elaborated for solid-phase synthesis of oligosaccharides. A propargyl glycoside-type linker between a sugar residue and a solid support was formed by the Sonogashira reaction of a propargyl glycoside with polymer-supported iodobenzene. A propargyl ester-type linker was also constructed by the same reaction of a 4-(proparygyloxycarbonyl)benzyl
