Condensation of 2-amino-3, 4, 5, 6-tetrahydroimidazo[4,5,1-ij]quinolinium and 2-amino-2-pyrrolinium salts with β- dike tones

The corresponding 12,l,2,3-tetrahydropyrimido2,12,3]imidazo4,5,1-ij]quinolinium and 7,8-dihydro-6H-pyrrolo1,2-a]pyrimidinium salts were obtained by the condensation of 2-amino-3,4,5,6-tetrahydroimidazo4,5,1-ij]quinoline hydrochloride and 2-amino-2-pyrroline hydrochloride with -diketones. The structures of the products of condensation with unsymmetrical diketones were determined from their PMR spectra.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 419–421, March, 1972.
