The anomerisation of glycosyl thiols and synthesis of multivalent GlcNAc and GalNAc glycoclusters
(2015-04-29)There are several published procedures available for the synthesis of b-thiopyranoses such as gluco- or galacto-pyranoses. Given the ease with which one can access such b -thiopyranoses, the development of a reproducible ... -
Carbohydrates as precursors to macrocyclic and iminosugar frameworks
(2017-09-30)Natural products have been perceived as privileged structures in drug discovery based on their evolutionary experience. Chapter 1, explores previous exploitation of this platform by medicinal chemists to identify some ... -
Development and Application of a Computational Method for Determining the Specificity of Glycan-binding Proteins
(2013-09-25)Changes in cell-surface glycan patterns are markers for the presence of many different disease and cancer types, offering a relatively untapped niche for glycan-targeting reagents and therapeutics in diagnosis and treatment. ... -
Studies in anomerisation of glycosyl thiols and glycosides
(NUI Galway, 2018-06-29)The stereoselective generation of 1,2-cis linkages continues to be a substantial challenge in carbohydrate chemistry today. Lewis acid-promoted anomerisation of 1,2-trans linkages offers a facile method to generate 1,2-cis ... -
Study of silyl protecting groups in anomerisation reactions: Total synthesis of a glycolipid from Plakortis simplex and its mimetics
(NUI Galway, 2019-02-04)This thesis deals with anomerisation, which is, in other words, epimerisation at the anomeric centre, usually interpreted as being from the equatorial to the axial anomer. An objective was to enhance the knowledge of this ... -
Synthesis of S-glycolipids and peptidomimetics
(2011-08-19)Chapters one and two of this thesis describe the synthesis of two novel glycosphingolipid derivatives. Glycosphingolipids are amphiphilic molecules consisting of a carbohydrate head group glycosidically linked to a sphingoid ...
