An asymmetric carbon center with a tetrafluoroethylene fragment can be efficiently constructed via a highly enantioselective conjugate addition reaction of various arylboronic acids with β-(bromotetrafluoroethyl)-α,β-unsaturated ketones. This system can be successfully applied to an enantiomerically enriched tetrafluoroethylenated liquid crystalline molecule.

通过各种芳基硼酸与β-(溴四氟乙基)-α,β-不饱和酮的高度对映选择性共轭加成反应,可以有效地构建具有四氟乙烯片段的不对称碳中心。该系统可以成功地应用于对映体富集的四氟乙烯化液晶分子。
