SUBSTITUTED 2- AND 4-BENZYLPYRIDINES IN THE SYNTHESIS OF BENZOQUINOLINES AND BENZOISOQUINOLINES

Article abstract of DOI:10.1007/BF00561353

Nitrogen-containing heterocyclic analogs of anthracene, viz., benzoisoquinolines and benzoquinolines, were obtained by dehydrocyclization on a K-16 catalyst of mixtures of methyl-substituted 2- and 4-benzylpyridines with methyl groups in various positions of the pyridine and benzyl rings, which are formed by benzylation of β-picoline, as well as pyridine, by the Ladenburg method.The spectral characteristics of the synthesized compounds are presented.
