  benzyl 2-O-benzyl-3,5-O-(1,1,3,3-tetraisopropyldisiloxane-1,3-diyl)-α-D-arabinofuranoside 在 ruthenium trichloride 、 sodium periodate 、 氯化亚砜 、 六氟异丙醇 、 四丁基氟化铵 、 三乙胺 作用下， 以 四氢呋喃 、 四氯化碳 、 二氯甲烷 、 水 、 乙腈 为溶剂， 反应 4.25h， 生成 benzyl 2-O-benzyl-5-deoxy-5-[2,3,5-tri-O-benzyl-1,4-dideoxy-1,4-episulfoniumylidene-D-arabinitol]-3-O-sulfoxy-α-D-arabinofuranose inner salt

  Synthesis of Sulfonium Sulfate Analogues of Disaccharides and Their Conversion to Chain-Extended Homologues of Salacinol: New Glycosidase Inhibitors

  摘要：

  [graphics]Four chain extended homologues of salacinol, a naturally occurring glycosidase inhibitor, were prepared for evaluation as inhibitors of glucosidase enzymes involved in the breakdown of carbohydrates. The syntheses involved the reactions of 1,4-anhydro-2,3,5-tri-O-benzyl-4-thiO-D-arabinitol with cyclic sulfate derivatives of different monosaccharides. Debenzylation of the products afforded the novel sulfonium sulfate derivatives Of D-glucose, D-galactose, D-arabinose, and D-Xylose that are of interest in their own right as glycosidase inhibitors. Reduction to the corresponding alditols then afforded the homologues of salacinol containing polyhydroxylated, acyclic chains of 5- and 6-carbons, differing in stereochemistry at the stereogenic centers. Three of the chain-extended homologues inhibited recombinant human maltase glucoamylase, one of the key intestinal enzymes involved in the breakdown of glucose oligosaccharides in the sinall intestine, with K-i values in the low microinolar range, of approximately the saine inagnitude as salacinol, thus providing lead candidates for the treatment of Type 2 diabetes.
