Abstract
The regioselective radiofluorodestannylation of 6-trimethylstannyl-L-m-tyrosine derivative 6 with [18F]F2 and [18F]acetyl hypofluorite afforded, after acid hydrolysis, 6-[18F]fluoro-L-m-tyrosine (8a) in radiochemical yields of 23 and 17%, respectively. Similarly, 4-[18F]fluoro-L-m-tyrosine (13a) was synthesized in 11% radiochemical yield from the corresponding 4-trimethylstannyl-L-m-tyrosine derivative 11 using [18F]F2. The structural analyses of precursors (6,11), intermediates, and the final products (after 18F decay), were carried out by 1H, 13C, 19F, 119Sn-NMR and high resolution mass spectroscopy.Entities:
