4-N-aryl(benzyl)amino-4-hetaryl-1-butenes as building blocks in heterocyclic synthesis. 1. New route to 4,6-dimethyl-2-pyridylquinolines from the 4-N-p-methylphenylamino-4-pyridyl-1-butenes

Abstract:

Mediated-acid intramolecular cyclisation of 4-N-p-methylphenylamino-4-pyridyl-1-butenes 4-6 was used to obtain new C-2 pyridyl substituted 4,6-dimethyl-1,2,3,4-tetrahydroquinolines 7-9, which were oxidised then to their aromatic analogues 10-12 in good yields.
