Procedure:
To Pd2(dba)3CHCl3 (60.1 mg, 5 mol %) and PPh3 (60.9 mg, 20 mol %) under a nitrogen atmosphere was added anhydrous DMF (0.5 mL). The resulting precipitate was stirred at room temperature for 30 minutes during which time the colour changed from red to yellow/orange. To this was added 1-(2-diethylaminoethyl)-3-hydroxy-3-(2-chlorophenyl)-4-bromo-6-iodooxindole (626.4 mg, 1.16 mmol) dissolved in anhydrous DMF (1.0 mL). To the resulting red solution was then added Zn(CN)2. The resulting precipitate was then heated to 60° C. (bath temperature) and stirring was continued at that temperature for 4 hours. The mixture was allowed to cool to room temperature and diluted with EtOAc:toluene (1:1, 10 mL). The mixture was washed with H2O (6 mL). The aqueous phase was then extracted with EtOAc:toluene (1:1, 5 mL×5). The organic phases were combined and dried (anhydrous MgSO4). After filtration the solvent was removed in vacuo. The orange solid obtained was then purified by flash chromatography (silica gel, eluting 1% to 2% to 3%MeOH in CHCl3) to give the title compound as a light brown/orange solid (462.6 mg, 91%).

Procedure:
To a solution of 1-[(2S,3S,4S,5R,6S)-3,4,5-tribenzyloxy-6-[4-chloro-3-[(4-ethoxyphenyl)methyl]phenyl]-2-(hydroxymethyl)-6-methoxy-tetrahydropyran-2-yl]ethanol 8b (0.6 g, 0.80 mmol) in dichloromethane (20 mL) was added p-toluenesulfonic acid (27.5 mg, 0.16 mmol). The mixture was stirred at room temperature for 2 hours and quenched with 5 mL of saturated aqueous sodium bicarbonate. The resulting mixture was partitioned. The aqueous layer was extracted with dichloromethane (10 mL×2). The combined organic layers were washed with water (10 mL×2) and then saturated aqueous sodium chloride (10 mL×2), dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by silica gel chromatography eluted with PE/EtOAc(v/v)=10/1 to give the title compound 8c as coloeless oil (258 mg, 44.8%). The compound was characterized by the following spectroscopic data: 1H NMR (400 MHz, CDCl3) δ (ppm): 7.41 (s, 1H), 7.34 (m, 4H), 7.31-7.27 (m, 6H), 7.24 (m, 2H), 7.14 (m, 3H), 7.06 (d, 2H), 6.89-6.83 (m, 2H), 6.77-6.72 (m, 2H), 4.86 (m, 3H), 4.74 (d, 1H), 4.32 (dd, 1H), 4.23 (d, 1H), 4.08 (m, 1H), 4.05-3.98 (m, 3H), 3.98-3.89 (m, 3H), 3.77 (d, 1H), 3.68 (d, 1H), 3.64 (d, 1H), 1.56 (d, 3H), 1.38 (t, 3H).

Procedure:
3 g of methyl 2,3,6-tri-O-benzoyl-α-D-galactopyranoside 57 (Reist et al., J. Org. Chem 1965, 30, 2312) are introduced into dichloromethane and cooled to −30° C. Then 3.06 ml of [bis(2-methoxyethyl)amino]sulfur trifluoride (BAST) are added dropwise. The reaction solution is warmed to room temperature and stirred overnight. The mixture is diluted with dichloromethane, and the organic phase is extracted with H2O, NaHCO3 solution and saturated NaCl solution. The organic phase is dried over Na2SO4 and concentrated. The crude product is crystallized from ethyl acetate and heptane. 1.95 g of 58 are obtained as a colorless solid. C28H25FO8 (508.51) MS (ESI+) 526.18 (M+NH4+). Alternatively, the reaction can also be carried out using 2.8 eq. of diethylaminosulfur trifluoride (DAST); in this case, the reaction solution is refluxed for 18 h after the addition. The working up takes place in analogy to the above description.
