Stereoselective synthesis of (E)-monofluoroalkenes was achieved in one step by condensation of organolithium or Grignard reagents with 3,3,3-trifluoropropionates. Highly functionalized monofluoroalkenes were obtained in good to excellent yields and stereoselectivities.
(E)-单氟烯烃的立体选择性合成是通过有机锂或格氏试剂与 3,3,3-三氟丙酸酯的缩合一步实现的。以良好到极好的产率和立体选择性获得了高度官能化的单氟烯烃。
