Application
Sulfonamide Effective for the Introduction of Amino group
Experimental procedure: To a solution of PPh3 (6.23 g, 23.8 mmol) in THF (56 mL) under an atmosphere of nitrogen at 0 °C is added DIAD (3.85 g, 23.8 mmol). The reaction is stirred at 0 °C for 30 min before N-(tert-butoxycarbonyl)-p-toluenesulfonamide (5.37 g, 20.0 mmol) is added. The mixture is allowed to stir at 0 °C for 5 min followed by the addition of 1 (3.11 g, 19.8 mmol). The reaction is stirred at room temperature for 2.5 h before being concentrated under reduced pressure to give a crude oil. The oil is purified by flash column chromatography (silica gel, ethyl acetate:hexanes = 1:20) to generate 2 (7.54 g, 18.4 mmol, 93%) as orange oil.
