We describe herein a palladium-catalyzed Heck-type reaction of O-acetyl ketoximes and allylicalcohols to pyridines. This protocol allows robust synthesis of pyridines and azafluorenones in good to excellent yields with...

linyl)(carbonyl)(hydrido)ruthenium chloride exhibited extremely high efficiency toward the coupling cyclization of γ-amino alcohols with secondaryalcohols. The corresponding products, pyridine or quinoline derivatives, are obtained in good to high isolated yields. On comparison with literature catalysts whose noble-metal loading with respect to γ-amino alcohols reached 0.5–1.0 mol % for Ru and a record
