  Synthetic studies in butenonyl C-glycosides: Preparation of polyfunctional alkanonyl glycosides and their enzyme inhibitory activity

  摘要：

  A simple synthesis of phenyl butenoyl C-glycosides has been achieved by Aldol condensation of peracetylated glycosyl acetones with aromatic aldehydes followed by deacetylation with methanolic NaOMe. The selected butenoyl C-glycosides on conjugate addition of diethyl malonate resulted in polyfunctional alkanonyl glycosides in good yields. The butenoyl C- and alkanoyl C- glycosides were evaluated for their alpha-glucosidase, glucose-6-phosphatse and glycogen phosphorylase enzyme inhibitory activities in vitro. Three of the synthesized (3, 5 and 9) showed potent enzyme inhibitory activities as compared to standard drugs. Compounds 3, 5 and 9 were evaluated in vivo too displaying significant activity as compared to standard drugs acarbose and metformin. (C) 2009 Elsevier Ltd. All rights reserved.

  efficient and simple strategy for the synthesis of a diverse range of anthraquinone-based aryl-C-glycosides has been developed. It involves the sequential Diels–Alder reaction and oxidative aromatization with the preformed glycosyl diene and dienophiles. The glycosyl dienes were obtained from simple sugars by tandem one-pot substitution and elimination reaction.

  对于不同范围的蒽醌基芳基的合成的有效和简单的策略Ç -glycosides已经研制成功。它涉及顺序的Diels-Alder反应以及预先形成的糖基二烯和亲二烯体的氧化芳构化作用。通过串联一锅取代和消除反应从单糖获得糖基二烯。

  A series of beta-C-glycosylic ketones were prepared starting from D-glucose, D-xylose, D-mannose, and cellobiose. The beta-C-glycosylic ketones on aldol condensation with different aromatic aldehydes in the presence of a suitable organocatalyst led to the formation of respective C-(E)-cinnamoyl glycosides stereoselectively in good yields as precursors for the synthesis of biologically active compounds.
