摘要
The direct monofluorination of N-protected pyridone derivatives has been developed using a stable electrophilic fluorinating reagent, N-fluorobenzenesulfonimide (NFSI). Interestingly, the fluorine atom is regioselectively introduced at the position opposite the carbonyl group in the pyridone substrate during the reaction. This method is applicable to a wide range of substrates and allows the regioselective late-stage monofluorination of pyridone scaffolds.
