• A new synthesis of the oligosaccharide domain of acarbose

  Synthesis of the oligosaccharide domain of acarbose was reinvestigated and was optimally performed using a maltosidic acceptor, already bearing a alpha-D-Glc-(1-->4)-D-Glc bond, and a new D-fucopyranosyl donor. The crucial glycosylation step was improved by varying three different parameters and notably by focusing on the C-4 protecting group of the fucosyl residue, solvent and promoter. The resulting

  对阿卡波糖的寡糖结构域的合成进行了重新研究，并使用已经带有α-D-Glc-（1-4）-D-Glc键的麦芽糖受体和新的D-呋喃核糖基供体进行了优化。关键的糖基化步骤通过改变三个不同的参数得到了改善，特别是着眼于岩藻糖基残基，溶剂和促进剂的C-4保护基团。为了为设计新的阿卡波糖类似物打开进一步的衍生前景，将所得的三糖进一步转化为亲电子物质。用叠氮化物和硫氰酸根阴离子有效地进行了取代反应。还合成了另外两种可能有趣的三糖化合物，即C-4III胺和相应的异硫氰酸酯。
• Synthesis of 4′-O-acetyl-maltose and α-d-galactopyranosyl-(1→4)-d-glucopyranose for biochemical studies of amylose biosynthesis

  The chemical synthesis of the title compounds as maltose analogs, in which the non-reducing end is modified by acetylation of the 4'-OH group or by reversing its configuration, is reported. For synthesis of the 4'-O-acetylated analog, p-maltose was converted into its per-O-benzylated-4',6'-O-benzylidene derivative followed by removal of the benzylidene acetal function and selective silylation at C-6'. Acetylation at C-4' of the obtained silylated compound followed by removal of the benzyl ether protecting groups and subsequent desilylation afforded the desired analog. The other maltose analog was synthesized via the glycosidation reaction between the glycosyl donor, O-(2,3,4,6-tetra-O-benzyl-alpha/beta -D-galactopyranosyl)trichloroacetimidate and the glycosyl acceptor, phenyl 2,3,6-tri-O-benzyl-1-thio-beta -D-glucopyranoside followed by removal of the phenylthio group and debenzylation to provide the desired analog.
