An 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
公开了一种铁(II)催化的N-氟代苯磺酰亚胺(NFSI)通过C(5)-H键裂解的恶唑和噻唑直接酰亚胺化反应,可提供中等收率到优异收率的C5咪唑,具有广泛的底物范围。该反应代表了芳烃的第一个铁催化的CH酰亚胺化,其中NFSI用作酰亚胺化试剂,并潜在地构成了对C5官能化的唑的有效利用,具有重要的医学意义。
