YieldReaction ConditionsOperation in experiment
4 g With sodium hydrogencarbonate; In tetrahydrofuran; water; at 0 - 20℃; for 2.0h;Inert atmosphere; To a solution of (27?,47?)-4-amino- l-(tert- butoxycarbonyl)pyrrolidine-2-carboxylic acid (3 g, crude, 12.9 mmol) in Tetrahydrofuran (30 mL), 10% aqueous sodium bicarbonate solution (40 mL) was added. The solution was pre- cooled to 0 C, N-(9-Fluorenylmethoxycarbonyloxy)succinimide (4.37 g, 13 mmol) dissolved in tetrahydrofuran (20 mL) was then added. The reaction mixture was stirred for 2 h at room temperature and concentrated in vacuo to leave a residue which was dissolved in ethyl acetate (100 mL) and treated with saturated aqueous ammonium chloride solution. The mixture was extracted with ethyl acetate (3 xlOO mL) and the organic layers were collected, dried over anhydrous sodium sulfate, filtered, and concentrated to afford a crude residue, which was purified by silica gel flash chromatography (ethyl acetate : methanol = 70 : 30) to afford (2R,4R)- 4-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-l-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid (4 g) as a white solid. 1H NMR (400Hz, CDC13) delta 7.73-7.7 l(m, 2 H), 7.58-7.48 (m, 2 H), 7.37-7.33 (m, 2 H), 7.29-7.26 (m, 2 H), 4.29-4.16 (m, 5 H), 3.69-3.44 (m, 2 H), 2.45 (s, 1 H), 2.31-2.14 (m, 2 H), 1.43 (s, 9 H).
