Yield	Reaction Conditions	Operation in experiment
	With lithium triethylborohydride In tetrahydrofuran at -78℃; for 0.5h;	General procedure for synthesis of 8 and 11 General procedure: To a solution of 6 or 9 (2.0 mmol) in dry THF (8 mL) at -78 °C was added LiEt3BH (2.1 mL, 2.1 mmol, 1M in THF). After being stirred at -78 °C for 0.5 h, the reaction was quenched with saturated sodium bicarbonate aqueous solution then the mixture was extracted with EtOAc (30 mL3). The combined organic layers were washed with brine. Dried, filtrated and concentrated to give the crude product without further purification. The residue was dissolved in MeOH (8 mL) and montmorillonite K-10 (200 mg) was added, after being stirred at rt for overnight, the mixture was filtrated through a short silica gel and concentrated to give the N,O-acetal 7 or 10. To a solution of 7 or 10 (1.0 mmol) in DCE (4 mL) was added Sc(OTf)3 (0.5 mmol), then the mixture was heated at 60 °C for 1-2 h. After being cooled to rt, the reaction was quenched with saturated sodium bicarbonate aqueous solution then the mixture was extracted with EtOAc (30 mL3). The combined organic layers were washed with brine. Dried, filtrated and concentrated. The residue was purified by flash chromatography on silica gel to give 8 or 11.
	With diisobutylaluminium hydride In tetrahydrofuran at -78℃; for 2h; Inert atmosphere;	General Procedure for the Synthesis of 6 or 7 General procedure: To a solution of compound 14 or 15 (2.0 mmol) in dry THF (10 mL) was added DMAP (0.2 mmol) and Boc2O (5.0 mmol). After being stirred at room temperature for 12 h, the mixture was quenched with NH4Cl and extracted with EtOAc (30 mL × 3). The combined organic layers were washed with brine, dried over MgSO4, filtrated and concentrated. The residue was purified by flash chromatography on silica gel (PE/EA = 5:1) to give the desired product 16 or 17. The compound 16 or 17 (0.5 mmol) was dissolved in dry THF (3 mL) under Ar atmosphere. Then DIBAL-H (1 M, 1.5 equiv) was dropped slowly. After being stirred at -78 °C for 2 h, the mixture was quenched with EtOAc and potassium sodium tartrate, and extracted with EtOAc (20 mL × 3). The combined organic layers were washed with brine, dried over MgSO4, filtrated and concentrated, then obtained the crude product 6 or 7 to be used without purification because of its unstablity.
