Abstract: | New substituted pyridine bases of the aryl(-pyridyl)methane type were obtained from 1,2,5-trimethyl-4-piperidone by successive transformations. The new substituted pyridine bases were catalytically dehydrocyclized to di(tri)methylbenzo[g]isoquinolines.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1077–1084, August, 1976. |
