Abstract

AbstractAn iron(II)‐catalyzed direct imidation of oxazole and thiazole with N‐fluorobenzenesulfonimide (NFSI) through C(5)−H bond cleavage is disclosed, providing C5‐imidated azoles in moderate to excellent yields with broad substrate scope. This reaction represents the first iron‐catalyzed C−H imidation of arene where NFSI serves as the imidation reagent, and potentially constitutes an efficient access to C5‐functionalized azole with great medicinal significance.magnified image
