83% | With N-ethyl-N,N-diisopropylamine; bromo-tris(1-pyrrolidinyl)phosphonium hexafluorophosphate; In N,N-dimethyl-formamide; at 0 - 20℃;Cooling with ice; | To a solution of iV-(te/t-butoxycarbonyl)-0-(te/t-butyl)-L-tyrosine (805 mg, 2.39 mmol) in DMF (20 mL) was added N-methylisoamylamine (256 mg, 2.53 mmol) and DIPEA (0.85 <n="39"/>- -mL, 4.90 mmol). The reaction mixture was cooled with an ice-water bath and PyBrOP (1.11 g, 2.40 mmol) added. The reaction mixture was stirred at 0 0C for 5 hours and then allowed to warm to r.t. overnight. The reaction mixture was concentrated in vacuo. The residue was suspended in 0.2M aq HCl (50 mL) and extracted with DCM (3 x 50 mL). The combined DCM extracts were dried (MgSO4) and concentrated in vacuo to give tert-hvXyl (S)- 1 -(λ/-isopentyl-λ/-methylcarbamoyl)-2-(4-tert-butoxyphenyl)ethylcarbamate (832 mg, 83%) as a colourless gum. |

70% | Stage #1: iodobenzene With isopropylmagnesium chloride In tetrahydrofuran at 0℃; for 1h; Stage #2: methyl 3,3,3-trifluoropyruvate In tetrahydrofuran at -78 - 0℃; for 1h; Stage #3: N-methylisoamylamine In tetrahydrofuran at 0 - 20℃; | Representative procedure for the synthesis of a-hydroxy a-trifluoromethyl amides 8 General procedure: preparation of 3,3,3-trifluoro-2-hydroxy-1-morpholino-2-phenylpropan-1-one 8b (Table 2, entry 1). To a solution of phenyl iodide 5a (300 lL, 2.68 mmol)in THF (4 mL) at 0 C, isopropylmagnesium chloride in THF (1338 lL,2.68 mmol, 2 M) was added dropwise. After stirring at 0 C for 1 h, a solutionof methyl trifluoropyruvate 7a (273 lL, 2.68 mmol) in THF (3 mL) was addeddropwise at 78 C. The mixture was stirred at 78 C for 1 h and thenwarmed to 0 C, morpholine 6b (350 lL, 4.01 mmol) and isopropylmagnesiumchloride (2.0 mL, 4.01 mmol, 2 M) were added dropwise. At the end of theaddition, the external cooling was removed, and the reaction was aged at roomtemperature overnight. At 0 C, the reaction mixture was quenched with slowaddition of satd. NH4Cl and extracted with EtOAc. The combined organic layerswere dried over anhydrous Na2SO4, filtered, and concentrated in vacuo.Purification by flash chromatography (0-60% EtOAc/hexane) provided thedesired amide |
