With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.24621-61-2,(S)-Butane-1,3-diol,as a common compound, the synthetic route is as follows.
Production of (S)-3-Hydroxy-1-(p-toluenesulfonyloxy)butane In the same manner as in the first step of Production Example 32, the desired compound (77.5 g) was obtained as light brown oil from (S)-1,3-butanediol (30.0 g) and p-toluenesulfonyl chloride (69.8 g). The thus-obtained oil was immediately subjected to the next step.
24621-61-2 (S)-Butane-1,3-diol 446973, achiral-oxygen-ligands compound, is more and more widely used in various.
