The title compound 1b, an important intracellular pH indicator, is conveniently prepared in 44% overall yield from 1,3-difluoro-2-propanol (2). Key steps in this synthesis include oxidation of 2 to 1,3-difluoroacetone (3) in near quantitative yield using KMnO4/CuSO4 and the addition of trimethylsilyl cyanide to a phenyl glycinol protected imine. The efficiency of this process was enhanced further by use of crude reaction mixtures or their solutions.
标题化合物1b是一种重要的细胞内pH指示剂,可通过便捷地从1,3-二氟-2-丙醇(2)制备,总收率达44%。该合成关键步骤包括使用KMnO4/CuSO4将2氧化为接近定量产率的1,3-二氟丙酮(3),以及将三甲基硅基氰化物添加到苯基甘氨醇保护的亚胺中。通过使用粗反应混合物或其溶液,该过程的效率进一步提高。
