Preparation of tagged glucose as a key intermediate in the synthesis of branched oligosaccharides
摘要:
Tagged and activated D-glucose was introduced as a building block for branched oligosaccharides. This building block was the oligosaccharide branching point at which selectively the C-2 followed by the C-3 position can be glycosylated. After the activation of the C-1 position by oxidation of a thiophenyl group, the newly formed tagged oligosaccharide can be used as a glycoside donor. Synthetic procedures for the preparation of phthalimide-based tag molecules as well as tagged monosaccharides are presented. (C) 2011 Elsevier Ltd. All rights reserved.

range of trans-A2B-corroles in acceptable yields. Spectroscopic properties of all five dyads studied suggest that regardless the imide's structure, components are weakly electronically coupled. Positioning 2,3-naphthalimide unit partially above the corrole core leads to slight alteration of their optical properties. Dyads bearing blue-absorbing imide components display different behavior depending on their
