1-(p-Toluenesulfonyl)imidazole was used in the synthesis of cationic water soluble cyclodextrin, mono-6A-(1-butyl-3-imidazolium)-6A-deoxy-β-cyclodextrin chloride (BIMCD), useful in chiral separation of amino acids and anionic pharmaceuticals by capillary electrophoresis. | [Uses]

1-(p-Toluenesulfonyl)imidazole converts alcohols to azides in one step. | [Synthesis]
(a) In a three-necked round-bottomed flask equipped with a charging funnel, oil collector, magnetic stirring bar and protected by argon, imidazole (5.502 g, 0.081 mol) was dissolved in 25 mL of anhydrous dichloromethane. After cooling the solution to 0°C, p-toluenesulfonyl chloride (6.78 g, 0.036 mol) dissolved in 25 mL of anhydrous dichloromethane was added slowly and dropwise. The reaction mixture was stirred at room temperature for 2 h. The reaction mixture was subsequently filtered through silica gel and the residual solid was washed with 50 mL hexane/ethyl acetate (1:1, v/v). The filtrate was concentrated in a rotary evaporator, redissolved in 6 mL of ethyl acetate and precipitation was induced by the addition of 60 mL of hexane. The resulting white solid was filtered and dried to give 7.12 g of 1-tosylimidazole (0.032 mol, 89% yield). | [References]
