PROCEDURE

实验过程

To a slurry of 2-(3-(N′,N″-di(t-butoxycarbonyl)guanidino)phenyl)-2-((1R)-(1-(benzylsulfonyl)amino-2-methylpropyl)(hydroxy)phosphinoyloxy)ethanoic acid methyl ester (0.53 mmol) in 6 mL of methanol and 3 mL of H2O was added LiOH (124.3 mg, 5.3 mmol). After stirring for 6 hours, the solution was acidified to pH 2 with concentrated HCl and extracted with methylene chloride (3×). The combined organic layers were dried over MgSO4, filtered, and concentrated in vacuo to give 2-(3-(N′,N″-di(t-butoxycarbonyl)guanidino)phenyl)-2-((1R)-(1-(benzylsulfonyl)amino-2-methylpropyl)(hydroxy)phosphinoyloxy)ethanoic acid as a yellow oil that was used without further purification in the following step.
