  D-核糖的螺乙内酰脲作为新的有效酶抑制剂。

  摘要：

  来自单糖的端粒螺乙内酰脲衍生物具有多种生物学特性。我们在本文中描述了D-阿洛糖和D-核糖的3-螺乙胆苷衍生物的合成。关键步骤是使用四异丙氧基钛作为温和有效的催化剂，由D-葡萄糖和D-木糖的蔗糖衍生物形成立体选择性的糖-α-氨基腈。从这些中间体合成了目标化合物。在酸性条件下，该糖部分被部分或完全脱保护。这些新的杂环单糖衍生物是有效的糖原磷酸化酶抑制剂。

  Stereoselective synthesis of α-aminonitriles at non-anomeric positions of monosaccharides

  摘要：

  alpha-Aminonitriles have been stereoselectively introduced at non-anomeric positions of monosaccharides, in which the carbon C-alpha is one of the atoms of the sugar ring. Target compounds were prepared from various ulose derivatives and amines using titanium(IV) isopropoxide as a mild and effective Lewis acid. (C) 2000 Elsevier Science Ltd. All rights reserved.

  Direct aldol reactions of acetone with aromatic aldehydes have been achieved in high yielding and enantioselective processes using glycosyl-alpha-aminotetrazoles as a new class of organocatalysts. Computational studies at DFT level have been performed to account for the experimental observations. (C) 2013 Elsevier Ltd. All rights reserved.

  The synthesis of 3-spirohydantoin derivatives of D-allose and D-ribose is reported. The key step is the stereoselective conversion of glyco-alpha -aminonitriles from ulose derivatives of D-glucose and D-xylose using titanium(IV) isopropoxide as a mild and efficient catalyst. Cyclisation of the glyco-alpha -aminonitriles give the target spirohydantoins. (C) 2001 Elsevier Science Ltd. All rights reserved.

  4-Amino-5-H-2,3-dihydroisothiazole-1,1-dioxide ring was attached to a monosaccharide ring system by carbanion-mediated sulfonate intramolecular cyclisation (CSIC) of either secondary or tertiary aminonitrilesulfonamide carbohydrate derivatives using NaH, Cs2CO3, or BuLi as a base. These new bicyclic systems were used as glycone precursors of aza analogues of TSAO RT inhibitors. We report the first synthesis of an aza analogue of TSAO-m(3)T. (C) 2001 Elsevier Science Ltd.
