Solid-phase carbohydrate synthesis via on-bead protecting group chemistry
摘要:
Di- and tri-saccharides were synthesized on a solid phase. The procedure started with a non-protected sugar linked via either cysteine or glutamine to a polystyrene resin. Selective dimethoxytritylation chemistry and subsequent steps yielded a resin-bound acceptor that could be glycosylated to yield beta 1,6-linked disaccharides. Reiteration of the procedure produced the trisaccharide. (C) 2007 Elsevier Ltd. All rights reserved.
