title: A series of 2-O-trifluoromethylsulfonyl-D-mannopyranosides as precursors for concomitant 18F-labeling and glycosylation by click chemistry.
abstract: A series of 'clickable' mannopyranosides bearing a triflate leaving group at C-2 position were synthesized and tested for their potential as (18)F-labeling precursors. 3,4,6-Tri-O-acetyl-2-O-trifluoromethanesulfonyl-beta-D-mannopyranosyl azide (2beta) was the most convenient precursor for a site-specific and reliable click chemistry-based three-step, two-pot concomitant (18)F-labeling and glycosylation of an alkyne-functionalized amino acid derivative.
