Rhodium-catalyzed chelation-assisted activation of the β-C-H bond of α,β-unsaturated ketoximes and subsequent reaction with alkynes affords highly substituted pyridine derivatives. This new method provides an opportunity for the one-pot synthesis of pyridines with all five positions (C2-C6) substituted.
