The highly enantioselective synthesis of 1,1,1-trifluoroalkan-2-ols has been achieved by hydrogenating 1,1,1-trifluoroalkan-2-one enol acetates in the presence of chiral ruthenium catalysts. An enol acetate, 2-acetoxy-3,3,3-trifluoro-1-(phenylthio)propene, can be successfully transformed into enantiomerically pure trifluorolactic acid.
在手性钌催化剂的存在下,通过氢化1,1,1-三氟烷-2-酮烯醇乙酸酯可以实现1,1,1-三氟烷-2-酮烯醇的高度对映选择性合成。烯醇乙酸酯2-乙酰氧基-3,3,3-三氟-1-(苯硫基)丙烯可成功转化为对映体纯的三氟乳酸。
