Synthesis of [¹⁸F]-γ-fluoro-α,β,-unsaturated esters and ketones via vinylogous ¹⁸F-fluorination of α-diazoacetates with [¹⁸F]AgF.

ABSTRACT: This communication reports a method for the vinylogous radiofluorination of α-diazoacetates to generate γ-[¹⁸F]fluoro-α,β-unsaturated esters and ketones in moderate to good radiochemical yields. The method uses no-carrier-added [¹⁸F]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 5-cholesten-3-one derivative as well as a difluorinated product pertinent to drug discovery.
