A hyperbranched star polymer was employed as a soluble support for disaccharide synthesis as a practical alternative to a dendrimer support. The large number of terminal groups present on the support permit very high loading levels to be possible. Polymer bound intermediates could be directly analyzed by MALDI-TOF mass spectrometry due to the presence of a photolabile linker that is cleaved by the MALDI-TOF laser.

Glycosyl donors and accepters may be covalently linked to aspartic acid residues via OH-6 esters. Peptide elaboration allows glycosylation reactions to be performed between donors and accepters linked to this peptide template. These reactions display increased regio- and stereoselectivities, which are dependent on the nature of the peptide. Simple molecular modelling is used to rationalise the differing product distributions obtained by variation of the linking amino acid sequence. (C) 2000 Elsevier Science Ltd. All rights reserved.
