Reaction Steps

3-[(4′-Methoxy[1,1′-biphenyl]-4-yl)sulfonyl]amino-2-oxo-5-[(1H-1,2,4-triazol-3-ylthio)methyl]-tetrahydrofuran: To a solution of methyl 2-[(4′-methoxy[1,1′-biphenyl]-4-yl)sulfonyl]amino-4,5-epoxypentanoate 1d (0.7 g, 1.79 mmol) in benzene (6 mL) and Et3N (0.33 mL, 2.3 mmol) at room temperature is added slowly 1H-1,2,4-mercaptotriazole (0.47 g, 4.48 mmol). The reaction mixture is stirred overnight at room temperature. Diluted with water, the mixture is extracted three times with EtOAc. The combined EtOAc layer is washed with water, brine, dried over MgSO4 and concentrated to an oil which is purified by column chromatography eluting with hexane/EtOAc (1:1) to give the desired product.
