24621-61-2, (S)-Butane-1,3-diol is a chiral-oxygen-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a stirring solution of (S)-1, 3-butanediol (1.0 g, 0.01 MMOL) and triethylamine (1.39 g, 0.014 MMOL) in dichloromethane (10 mL) at-20C was added dropwise p- toluenesulfonyl chloride and the mixture was stirred for 2 h. The reaction mixture was then warmed to RT and stirred overnight. The reaction mixture was poured into cold H20 (20 mL), and extracted three times with DICHLOROMETHANE. The organic extracts were then washed with brine. The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo to give 2.6 g (96% yield) of title compound as an oil. MS (ESI) 244.8 (M+). The crude tosylat was used without further purification.
As the paragraph descriping shows that 24621-61-2 is playing an increasingly important role.
