YieldReaction ConditionsOperation in experiment
45% With hydrogenchloride In water; acetone at 18 - 20℃; for 0.0833333 h; To a solution of the orthoester4(4.4 g, 12 mmol) in anhydrous acetone (27 mL) was added 1M hydrochloric acid (HCl) aq. (2.7 mL) in one portion with vigorous stirring (~18°C, water bath). After being stirred for an additional 5 min at room temperature, the reaction mixture was concentrated on a rotary evaporator below 20°C. The resulting solid was dissolved in CHCl3(25 mL) and washed with water (2 × 10 mL). The organic layer was dried over anhydrous Na2SO4, filtered, and concentrated on a rotary evaporator. The residue was triturated with diethyl ether (Et2O) and recrystallized from EtOH to yield the tetraacetyl mannose5(1.9 g, 45percent) as a white solid.Rfvalue 0.13 (hexane : EtOAc = 1 : 1). m.p. 134–136°C. HRMS (ESI):m/zfor C14H20NaO10([M+Na]+) cacld 371.09542, found 71.09581 (error 0.39 mmu, 1.06 ppm).
26% With hydrogenchloride In water; acetone at 20℃; for 0.166667 h; To a solution of compound 10 (11.24 g, 30 mmol) in acetone (40 ml),1M HCl (aq) was added in one portion while vigorously stirring in a water bath. The mixture was stirred at room temperature for 10 min. It was then concentrated under reduced pressure. CHCl3 was added. The resulting mixture was washed with water. After separation, the organic layer was dried over Na2SO4, concentrated, and washed with ether and EtOH to give 2.73 g of 11 as a white solid. Yield: 26percent.

YieldReaction ConditionsOperation in experiment
56% With pyridine In dichloromethane at -15 - 20℃; Inert atmosphere The tetraacetyl mannose5(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 a period of 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(1.4 g, 56percent).Rfvalue 0.5 (hexane : EtOAc = 1 : 1).
