Popis: | Variously N,N-disubstituted chiral dibromofluoromethylphosphonamides 3 were easily prepared and used for the asymmetric electrosynthesis, in the presence of tert-butyl acrylate, of α-fluorinated cyclopropylphosphonamides 7. The diastereoisomeric excesses are moderate (up to 40%). Moreover, the identification of the trans and cis stereoisomers has been deduced from analysis of 2D 1H–19F HOESY spectra. |
