  Chemical Synthesis of Hydroxycinnamic Acid Glucosides and Evaluation of Their Ability To Stabilize Natural Colors via Anthocyanin Copigmentation

  摘要：

  This work describes the chemical synthesis of O-aryi-beta-D-glucosides and 1 -O-beta-D-glucosyl esters of hydroxycinnamic acids. In particular, OLaryl-beta-D-glucosides were efficiently prepared via a simple diastereoselective glycosylation procedure using phase transfer conditions. Despite the lability of its ester linkage, 1-O-beta-D-caffeoylglucose could also be obtained using a Lewis acid catalyzed glycosylation step and a set of protective groups that can be removed under neutral conditions. Hydroxycinnamic acid O-aryl-beta-D-glucosides were then quantitatively investigated for their affinity for the naturally occurring anthocyanin malvin (pigment). Formation of the pi-stacking molecular complexes (copigmentation) was characterized in terms of binding constants and enthalpy and entropy changes. The glucosyl moiety did not significantly alter these thermodynamic parameters, in line with a binding process solely involving the polyphenolic nuclei.

• Stereoselective synthesis of 1-O-β-feruloyl and 1-O-β-sinapoyl glucopyranoses

  1-O-beta-Feruloyl and 1-O-beta-sinapoyl glucopyranoses are two common substrates for serine carboxypeptidase-like acyltransferases and serve as acyl donors in the biosynthesis of numerous secondary metabolites. In addition, they are involved in plant cell wall cross-linking and are also ideal substrates for studying the kinetics of lignification involving hydroxycinnamates. We report the first chemical (and multi-gram scale) synthesis of 1-O-beta-feruloyl and 1-O-beta-sinapoyl glucopyranoses. (C) 2011 Elsevier Ltd. All rights reserved.
