1,1,1-Trifluoro-3-(phenylthio)propan-2-ol was prepared in high enantiomeric purity by lipase-mediated kinetic resolution of the corresponding esters. The resolved alcohol was successfully converted into 1,1,1-trifluoro-2,3-epoxypropane and/or used in the subsequent reactions as latent 1,1,1-trifluoro-2,3-epoxypropane via sulfonium salt formation.
通过脂肪酶介导的相应酯类的动力学解析,制备出了对映体纯度很高的 1,1,1-三氟-3-(苯硫基)丙-2-醇。解析出的醇通过形成锍盐成功地转化为 1,1,1-三氟-2,3-环氧丙烷和/或在随后的反应中用作潜伏的 1,1,1-三氟-2,3-环氧丙烷。
