We describe herein a general and efficient synthetic approach toward substituted pyridines from functionalized N-acy1-2,3-dihydropyridones in two steps; 1,2-addition with organocerium reagents and subsequent oxidative aromatization with chloranil. This strategy allows the generation of pyridines with various substitution patterns and introduces a variety of substituents including aryl, alkyl, alkynyl, alkenyl, and heteroaryl groups at the desired positions.
