Monofluoroalkenes bearing a malonate unit at the β position can be synthesized by the enantioselective addition of diesters to 3,3-difluoropropenes. The difference in reactivity regarding the geometry and the substituents of the alkene of the 3,3-difluoropropenes, as well as the alkyl groups of the malonates, was studied and limitations were identified. The reaction was also performed with different
在β位置带有丙二酸酯单元的一氟烯烃可以通过将二酯对映选择性地加成到3,3-二氟丙烯中来合成。研究了关于3,3-二氟丙烯的烯烃的几何形状和取代基以及丙二酸酯的烷基的反应性差异,并确定了局限性。该反应也用不同的3,3-二氟丙烯进行。还完成了新官能化的单氟烯烃的进一步合成转化。
