The stereoselective synthesis of 3-fluoro-2-alkenoic acids was achieved by the reaction of lithium 3,3,3-trifluoropropionate with Grignard reagents. 2,2,2-Trifluoroethyl alkyl ketones were prepared by the reaction of 3,3,3-trifluoropropionic acid chloride with either lithium dialkylcuprates or magnesium dialkylcuprates. Optically active 1,1,1 -trifluoro-3-alkanols were obtained by the enzymatic hydrolysis
通过3,3,3-三氟丙酸锂与格利雅试剂的反应实现了3-氟-2-链烯酸的立体选择性合成。通过3,3,3-三氟丙酸酰氯与二烷基铜酸锂或二烷基铜酸镁的反应制备2,2,2-三氟乙基烷基酮。通过相应的乙酸酯的酶促水解获得旋光的1,1,1-三氟-3-链烷醇。
