YieldReaction ConditionsOperation in experiment
93% With 1H-imidazole; In DMF (N,N-dimethyl-formamide); at 0 - 20℃; for 3.0h; (R)-tert-butyl 3- hydroxy-l- (methoxy (methyl) amino)-l-oxopropan-2-ylcarbamate (21) (4.4 g, 17.5 mmol, 1.0 equiv. ) was added to a 100 mL RBF followed by DMF (35 mL) and cooled to 0 C via an ice bath. Next, TBDMSC1 (2.9 g, 19.3 mmol, 1.1 equiv. ) and imidazole (2.4 g, 35.1 mmol, 2.0 equiv. ) were added to the reaction flask. The solution was stirred at 0 C for 1 h and then allowed to warm to rt, stirring an additional 2 h. The reaction solution was transferred to a 500 mL separatory funnel with EtOAc (150 mL). The mixture was washed with 1% HCl (3 x 40 mL), sat. NaHCO3 (1 x 40 mL), and sat. NaCl (2 x 40 mL). The organic layer was separated and dried over Na2S04. The solution was concentrated on a rotary evaporator and dried under vacuum to give 5.9 g (93%) of 22 as a colorless oil.

89% With 1H-imidazole; dmap; In N,N-dimethyl-formamide; at 20℃; for 2.0h; [0118] To a solution of tert-butyl N-[(1R)-1-(hydroxymethyl)-2-[methoxy(methyl)amino]-2-oxoethyl]carbamate (5a)(5.42 g, 21.8 mmol), imidazole (4.46 g, 65.5 mmol) and DMAP (133 mg, 1.1 mmol) in anhydrous DMF (17 mL) at rt wasportionwise added tert-butyldimethylsilyl chloride (3.95 g, 26.2 mmol). The mixture was stirred for 2 h then poured inH2O (50 mL). The aqueous layer was extracted with EtOAc (2 x 40 mL). The organic layer was washed with 1 M HCl(50 mL), brine (40 mL), dried over Na2SO4 and concentrated in vacuo. The residue was purified by flash chromatographyon silica gel (cyclohexane/EtOAc 100/0 to 50/50) to provide tert-butyl N-[(1R)-1-[[tert-butyl(dimethyl)silyl]oxymethyl]-2-[methoxy(methyl)amino]-2-oxo-ethyl]carbamate (5b) (7.09 g, 19.5 mmol, 89%) as a colorless oil.MS m/z ([M+Na]+) 385, ([M+H]+) 363.1H NMR (400 MHz, CDCl3) delta 0.03 (s, 6H), 0.87 (s, 9H), 1.44 (s, 9H), 3.21 (s, 3H), 3.64-3.94 (m, 5H), 4.75 (s, 1 H), 5.35(d, J = 9.0 Hz, 1H).
