摘　　要：A rhodium-catalyzed dearomative rearrangement reaction of 2-oxypyridines has been developed by using cyclopropenes as carbene precursors.This protocol features broad substrate scope and mild reac-tion conditions,providing a reliable and practical approach for the highly efficient synthesis of 2-alkylated 2-pyridone derivatives from readily available O-substituted pyridine compounds.
