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

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.

Rhodium-catalyzed one-pot synthesis of substituted pyridine derivatives from α,β-unsaturated ketoximes and alkynes

(Chemical Equation Presented) A rhodium-catalyzed chelation-assisted C-H activation of α,β-unsaturated ketoximes and the reaction with alkynes to afford highly substituted pyridine derivatives is described.

CYCLOADDITION REACTIONS WITH AZABENZENES. XVIII. SYNTHESIS OF PYRINDINES

The reaction of 1,2,4-triazines (1) and 1-cyclopentenylpyrrolidine (2) afforded 6,7-dihydro-5H--pyrindines (3) in good yields.Oxidation of 3 to the N-oxides (4), reaction of 4 with acetic anhydride to 5-acetoxy-6,7-dihydro-5H-pyrindines (5) and elimination of acetic acid afforded pyrindines (7). 2-Methyl-2H-pyrindines (9) were also prepared.
