## Abstract This account concentrates on our new methodologies for the synthesis of fluorine analogues of amino acids and their derivatives using the Reformatsky‐type reactions of ethyl bromodifluoroacetate and ethyl dibromofluoroacetate with imines promoted by the Wilkinson catalyst. First, we pre

✦ Synopsis
The electrophilic imino esters XF 2 CC(=NPG)CO 2 Me and imino phosphonates CF 3 CC(=NPG)P(O)(OR) 2 (PG = SO 2 Ph, Cbz, Boc) were transformed by nucleophilic and then electrophilic additions into fluorine-containing amino esters and amino phosphonates with two pendent alkene chains

For the first time, an approach to cyclic ␣-amino phosphonate structures bearing a 5, 6benzo[1,3,2]diazaphosphorinan-4-one 2-oxide framework is described. The desired products, 4 and 5, were prepared by a modified Pudovik reaction, starting from the benzodiazaphosphorinanone derivative 1 and several
