Abstract
- This communication reports a method for the vinylogous radiofluorination of α-diazoacetates to generate [<superscript>18</superscript> F]-γ-fluoro-α,β-unsaturated esters and ketones in moderate to good radiochemical yields. The method uses no-carrier-added [<superscript>18</superscript> F]AgF and is compatible with aromatic and non-aromatic substrates and a number of different functional groups. The labeling method is showcased in the synthesis of a fluorinated cholest-5-en-3-one derivative as well as a difluorinated product pertinent to drug discovery. [ABSTRACT FROM AUTHOR]
