摘要
A facile synthetic method to substituted pyridines has been developed via the NH4I-catalyzed [4+2] cycloaddition of readily available oxime acetates with alkyl pyruvate. This process involves N-O bond cleavages and C-C bond formations to furnish substituted pyridines under redox-neutral conditions. The reaction features mild conditions and high functional-groups compatibility.
