An efficient rhodium-catalyzed dearomative rearrangement of 2-oxypyridines with quinone diazides has been developed for the direct synthesis of N-arylated pyridones, in which a novel 1,6-O-to-O rather than 1,4-O-to-C acyl rearrangement has been achieved under mild reaction conditions.
已开发出一种有效的铑催化的 2-氧吡啶与二叠氮醌的脱芳烃重排,用于直接合成N-芳基化吡啶酮,其中新型 1,6- O - 到 - O而不是 1,4- O - 到 - C酰基重排已在温和的反应条件下实现。
