  1,3,4,6-Tetra-O-acetyl-2-O-trifluoromethanesulfonyl-beta-D-mannopyranose is a radiolabelled pharmaceutical preparation for diagnostic aims used in positron emission tomography.

• synthetische

  The tetraacetyl mannose (1.8 g, 5 mmol) was dissolved in anhydrous CH2Cl2(14 mL) containing dry pyridine (0.9 mL, 11 mmol). This solution was cooled to -15°C, and trifluoromethanesulfonic anhydride (triflic anhydride) (0.9 mL, 5.2 mmol) was added dropwise over 25 min under a nitrogen atmosphere with vigorous stirring. The mixture was then allowed to reach room temperature overnight. The reaction mixture was successively washed with ice-cold saturated aqueous NaHCO3(50 mL) and water (50 mL). The organic layer was dried over anhydrous Na2SO4, filtered, and concentrated on a rotary evaporator.2-Tf-O-AcManwas isolated by column chromatography on silica with hexane :EtOAc=1: 1 as the eluant as white solid Mannose triflate(1.4 g, 56percent).
