SYNTHESIS OF ALKENYLQUINOLINES AND CYCLIZATION OF (1-METHYL-2-BUTENYL)QUINALDINES IN POLYPHOSPHORIC ACID

Abdrakhmanov, I. B.,Khalilov, I. N.,Mustafin, A. G.,Tolstikov, G. A.

, p. 1137 - 1139 (1990)

The reaction of 2- and 4-alkenylanilines with paraldehyde gave 6- and 8-alkenylquinaldines.Heating 8-(1'-methyl-2'-butenyl)quinaldines in polyphosphoric acid leads to the formation of tricyclic compounds with isomerization of the alkenyl group.
