Synthesis of pyridines from ketoximes and terminal alkynes via C-H bond functionalization.

ABSTRACT: An expedient one-pot rhodium catalyzed C-H bond functionalization/electrocyclization/dehydration procedure has been developed for the synthesis of highly substituted pyridine derivatives from terminal alkynes and α,β-unsaturated ketoximes. The use of electron-deficient phosphite ligands is important to suppress dimerization of the terminal alkynes to enynes.
