## Abstract The synthesis of 4β[^18^F] fluoroproline is described, but attempts to prepare 3β[^18^F] fluoroalanine failed. In the synthetic pathway to this compound different routes are investigated to make a labeled precursor, __viz__ [^18^F] fluoromethyliodide, which, however, were unsuccessful.
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 [Z = CO 2 Me, P(O
