  Convenient one-pot synthesis of thiosugars and their efficient conversion to polyoxygenated cycloalkenes

  摘要：

  A convenient synthesis of polyoxygenated tetrahydrothiopyrans and thiepanes from various alditol derivatives with xylo, ribo, manno, gluco, galacto, and fuco configurations is described. The preparation started from the corresponding partially protected alditols and proceeded in a 'one-pot' manner to afford the final products in 80%-95% yield. Furthermore, thiosugar compounds 2b, 2d, and 2g were converted to the optically pure polyoxygenated cycloalkenes through Ramberg-Backlund reaction in moderate to good overall yield. The procedures can be used for the preparation of polyoxygenated thiosugars and cycloalkenes on a relatively large scale. (C) 2012 Elsevier Ltd. All rights reserved.

  摘要：

  报道了 N-烷基化脱氧野尻霉素和具有 D-或 L-赤藓糖醇-3-硫酸酯官能化 N-取代基的 1,5-dideoxy-1,5-亚氨基木糖醇衍生物的合成。所用的烷基化剂是环状硫酸盐衍生物，由此选择性地攻击受阻最小的一级中心处的氮原子，得到所需的铵盐。在水溶液中，这些盐在铵中心的构型不稳定。铵盐的锍和/或硒鎓类似物通过类似反应制备。硫属元素盐是作为非对映异构体的混合物获得的，在某些情况下是可分离的，仅在构型稳定的硫或硒原子的立体化学上有所不同。通过详细的 NMR 实验获得了每种化合物的构型和构象的证据。这些化合物是 salacinol 的六元环类似物，是一种已知的锍盐葡萄糖苷酶抑制剂。对目标化合物对葡糖苷酶葡糖淀粉酶 G2 的酶抑制作用的评估表明，这些化合物要么是无活性的，要么最多只是麦芽糖水解的弱抑制剂。

  A method for synthesizing Salacinol, its stereoisomers, and analogues, homologues and other derivatives thereof potentially useful as glycolsidase inhibitors. The compounds of the invention may have the general formula (I) or (II): The synthetic schemes comprise reacting a cyclic sulfate with a 5-membered ring sugar containing a heteroatom (X). The heteroatom preferably comprises sulfur, selenium, or nitrogen. The cyclic sulfate and ring sugar reagents may be readily prepared from carbohydrate precursors, such as D-glucose, L-glucose, D-xylose and L-xylose. The target compounds are prepared by opening of the cyclic sulfates by nucleophilic attack of the heteroatoms on the 5-membered ring sugars. The resulting heterocyclic compounds have a stable, inner salt structure comprising a heteroatom cation and a sulfate anion. The synthetic schemes yield various stereoisomers of the target compounds in moderate to good yields with limited side-reactions.

  [FR] L'invention concerne des procédés servant à synthétiser du Salacinol, ses stéréoisomères et des analogues, des homologues et autres dérivés de ceux-ci potentiellement utiles en tant qu'inhibiteurs de glycosidases. Dans certains modes de réalisation, les composés de l'invention peuvent répondre à la formule générale (I) ou (II). Les schémas de synthèse peuvent consister à faire réagir un sulfate cyclique avec un sucre cyclique à 5 chaînons contenant un hétéroatome (X). L'hétéroatome est de préférence le soufre, le sélénium ou l'azote. On peut aisément préparer les réactifs que sont le sulfate cyclique et le sucre cyclique à partir de précurseurs de type glucides tels que le D-glucose, le L-glucose, le D-xylose et le L-xylose. On prépare les composés cibles en ouvrant les sulfates cycliques par attaque nucléophile des hétéroatomes sur les sucres cycliques à 5 chaînons. Les composés hétérocycliques résultants ont une structure de sel interne stable comprenant un cation d'un hétéroatome et un anion sulfate. Les schémas de synthèse produisent différents stéréoisomères des composés cibles avec des rendements de production moyens à bons et avec des réactions secondaires limitées. L'invention concerne également des analogues par extension de chaîne du Salacinol.
