  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.

  Aldol reaction of β-C-glycosylic ketones: synthesis of C-(E)-cinnamoyl glycosylic compounds as precursors for new biologically active C-glycosides

  摘要：

  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.
