N,N-Bis(perfluoroalkyl)thiocarbamoyl chlorides (FDMTC-Cls) were synthesized as reagent for the protection of alcohols. Using the crystalline FDMTC-Cls, the FDMTC groups were introduced into the alcohol molecules in excellent yields in the presence of sodium hydride in THF at room temperature. The products were separated from the excess alcohols by solid-phase extraction with a fluorous reverse-phase
合成了N,N-双(全氟烷基)硫代氨基甲酰氯(F DMTC-Cls)作为保护醇的试剂。使用结晶的F DMTC- Cl,在室温下在THF中存在氢化钠的情况下,将F DMTC基团以优异的产率引入醇分子中。通过用氟反相硅胶柱进行固相萃取(Fluorous固相萃取; FSPE),将产物与过量的醇分离。所述˚F DMTC组分别容易地通过用氧化除去米氯过苯甲酸(米-CPBA)中,用KHCO随后水解3。
