  摘要：

  通过在t-BuOK存在下丁烯酰基C-糖苷（5a-5j和8）与氰基乙酰胺的反应，然后进一步修饰，合成了一系列吡喃糖基-C-核苷。该反应通过将氰基乙酰胺迈克尔加成到丁烯酰基C-糖苷中，然后进行脱水环化和氧化芳构化而得到糖基甲基吡啶酮（6a-6j，7a-7j，9和10）。与POCl（3）在回流下反应的糖基甲基吡啶酮（6a-6e）以良好的产率得到了相应的糖基甲基吡啶（11a-11e和12a-12e）。筛选合成的化合物的体外α-葡萄糖苷酶，葡萄糖-6-磷酸酶和糖原磷酸化酶抑制活性。吡啶甲基甲基-C-核苷之一，化合物11d，

  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.

  One pot synthesis of the butenonyl-C-beta-D-glycosides with malononitrile in the presence of K2CO3 in water under mild and green reaction conditions leading to the formation of small library of multifunctional biphenyl methyl-C-beta-D-glycosides in good yields has been reported. The reaction is equally applicable with the substrates having different glycosyl pyranoses and aromatic rings with different substituents. (C) 2010 Elsevier Ltd. All rights reserved.
