A 2-fluoro-1,3-dicarbonyl-initiated one-pot Michael addition/[5 + 1] annulation/dehydrofluorinative aromatization reaction sequence enables a transition-metal catalyst-free, regioselective synthesis of di-, tri-, tetra-, and pentasubstituted pyridines as well as fused pyridines from readily available starting materials.
