Reactions of cycloammonium cations

2-Keto derivatives of N-acyl-1,2-dihydroquinoline and isoquinoline were obtained by the reaction of quinoline and isoquinoline with ketones and-dicarbonyl compounds in the presence of acyl halides. Under similar conditions, 9-phenacylacridines are formed by the reaction of acridine with acetophenones and acyl halides, while 5-acyl-6-phenacyl-5,6-dihydrophenanthridines are formed in the reaction of phenanthridine.See [1] for communication X.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 643–647, May, 1971.
