YieldReaction ConditionsOperation in experiment
1H-Tetrazole (0.34 g, 4.8 mmol) was added to a solution of the reducingsugar S1 (2.2 g, 4.0mmol) and i-Pr2NP(OMe)2(1.0 mL, 4.4 mmol) in dry CH2Cl2 (12 mL) at 0 C. Themixture was stirred for 5 min and then warmed to rt. Dry CH2Cl2(4.0 mL) was added twice every 12 min to dissolve 1H-tetrazole and the mixture was stirred for 10 min. Additional 1H-tetrazole (0.34 g, 4.8 mmol) was then addedto the mixture. After being stirred for 10 min, i-Pr2NP(OMe)2 (0.70 mL, 3.1 mmol) was addedto the solution, and the reaction was quenched with a saturated NaHCO3aqueous solution (20 mL) 30 min later. The mixture was extracted with CH2Cl2(200 mL) and then the organic layer was washed with saturated NaHCO3aqueous solutions (3 × 200 mL), dried over Na2SO4,filtered and concentrated under reduced pressure. The residue was dissolved in freshlydistilled THF (20 mL) and a solution of BH3?THF (0.99 M, 12 mL, 12mmol) in THF was added to the solution at 0 C. The reaction mixture wasstirred for 5 min and warmed to rt. The reaction mixture was then stirred for30 min and concentrated under reduced pressure. The residue was dissolved inCHCl3 (200 mL) and washed successively with saturated NaHCO3aqueous solutions (2 × 200 mL) and with a mixture of brine (100 mL) and asaturated NaHCO3 aqueous solution (100 mL). The aqueous layer wasback-extracted with CHCl3 (100 mL). The combined organic layers weredried over Na2SO4, filterd and concentrated under reducedpressure. Purification of the residue by silica gel column chromatography[hexane-AcOEt (6:1 to 4:1, v/v)] gave 1 as a colorless syrup (2.5 g, 3.9 mmol,96%, a/b = 74:26). The 1H and 31PNMR spectra were in good agrrement with reported data.1
