Selectfluor-mediated regioselective nucleophilic functionalization of N-heterocycles under metal- and base-free conditions

A practical and environmentally attractive methodology for the direct diversification of N-heterocycles at ambient temperature under open-air conditions was developed. The obvious advantage of the process is that no toxic reagent, transition metal, base or other additive is employed, thus greatly reducing costs, facilitating post-reaction neutralization and purification and minimizing the environmental impact.
