Concise assembly of linear α(1→6)-linked octamannan fluorescent probe

Academic Article

Abstract

  • Synthesis of a fluorescently labelled (dansylated) linear α(1→6)-linked octamannan, using glycosyl fluoride donors and thioglycosyl acceptors, is described. A selective and convergent two-stage activation progression was executed to construct di-, tetra, and octa-mannosyl thioglycosides in three glycosylation steps with excellent yield. Further, a 5-N,N-dimethylaminonaphthalene-1-sulfonamidoethyl (dansyl) group was coupled to 1-azidoethyl octamannosyl thioglycoside. Global deprotection of the coupled product afforded the desired dansylated homo-linear α(1→6)-linked octamannan. © 2008 Elsevier Ltd. All rights reserved.
