YieldReaction ConditionsOperation in experiment
57% In 2,2,2-trifluoroethanol; at 20℃; for 96h;Inert atmosphere; Step 2: (3R,4S)-tert-butyl 3-acetamido-4-allyl-3-(tert-butylcarbamoyl)pyrrolidine-l- carboxylate[0182] A stirred mixture of tert-butyl 3-allyl-4-oxopyrrolidine-l-carboxylate (13.23 g, 58.7 mmol) and ammonium acetate (11.95 g, 155 mmol) in 2,2,2-trifluoroethanol (25 mL) under nitrogen was treated with t-butylisonitrile (12.25 mL, 106 mmol), then stirred at room temperature for 4 days and concentrated. The residue was partitioned between water (100 mL) and methylene chloride (200 mL), and the aqueous layer was extracted with methylene chloride (2 x 75 mL). The combined organic solution was washed with water and saturated aqueous sodium chloride (100 mL each), dried (Na2S04), and concentrated to an off-white solid. This was recrystallized twice with ethyl acetate (150 mL each) to afford a portion of the title product (8.36 g) as a white solid. The combined mother liquors were concentrated, dissolved in minimum methylene chloride, and loaded onto a silica gel column (650 mL volume). This was eluted with 60%, then 70%, then 90%> ethyl acetate/heptane to afford additional product (3.84 g). Total yield of (3R,4S)-tert-butyl 3-acetamido-4-allyl-3-(tert- butylcarbamoyl)pyrrolidine-l-carboxylate was 12.22 g (57%) as a white solid. NMR(CDC13) delta 6.30 - 6.70 (m, 2 H), 5.60 -5.75 (m, 1 H), 4.95 - 5.10 (m, 2 H), 3.94 (d, J=11.5 Hz, 1 H), 3.75 (d, J=11.5 Hz, 1 H), 3.60 (m, 1 H), 3.00 - 3.20 (m, 2 H), 2.20 - 2.30 (m, 1 H), 2.00 (s, 3 H), 1.80 - 1.90 (m, 1 H), 1.44 (s, 9 H), 1.33 (s, 9 H).

YieldReaction ConditionsOperation in experiment
51% In 2,2,2-trifluoroethanol; at 60℃;Inert atmosphere; Example 46: preparation of (3R,4S)-3-amino-4-(3-boronopropyl)-l-(4- fluorobenzoyl)pyrrolidine-3-carboxylic acidStep 1: tert-Butyl 4-allyl-3-[ (2-nitrophenyl)carbamoyl]-3-[ (trifluoroacetyl) amino] - pyrrolidine- 1-carboxylate[0261] While under nitrogen, a stirred mixture of tert-butyl 3-allyl-4-oxopyrrolidine-l- carboxylate (600 mg, 2.66 mmol), ammonium trifluoroacetate (698 mg, 5.33 mmol) and 2- nitrophenyl isocyanide (690 mg, 4.6 mmol) in 2,2,2-trifluoroethanol (2.7 mL) was placed in a 60 C oil bath and stirred overnight. After cooling to room temperature, the mixture was diluted with ethyl acetate (40 mL), washed with water (3 x 20 mL) and the combined aqueous phase was re-extracted with ethyl acetate (20 mL). The combined organic phase was washed with saturated aqueous sodium chloride (20 mL), dried over Na2S04 and concentrated under reduced pressure. Purification by silica gel chromatography (90 g column, 0-5% ethyl acetate in methylene chloride) gave tert-butyl 4-allyl-3-[(2-nitrophenyl)carbamoyl]-3- [(trifluoroacetyl)amino] -pyrrolidine- 1-carboxylate (665 mg, 51%, 3:2 mixture ofdiastereomers) as an amber gum. LC-MS ESI + MS found for C2iH25F3N406 m/z 509.0 (M + Na). LC-MS ESI" MS found for C2iH25F3N406 m/z 485.1 (M - H).
