PROCEDURE

实验过程

To a solution of 4-isopropyl-6-hydroxy-2-phenylthiomethylsaccharin.(2.0 g, 5.509 mmol) in THF (35 mL) containing triphenylphosphine (1.59 g, 6.06mmol) and 2-(triisopropylsilyloxy) ethanol (1.13 g, 6.0 mmol) at room temperature was added diethylazodicarboxylate (1.04 mL, 6.6 mmol). The mixture was stirred overnight (16 hours), the solvent was removed in vacuo and the residue was purified by column chromatography on silica eluting with 10% ethyl acetate/hexane to afford 2.66 g (86%)of 4-isopropyl-6-[2-(triisopropylsilyloxy)ethoxy]-2-phenylthiomethylsaccharin as an oil
