Polycondensed Nitrogen Heterocycles. Part 23. Pyrrolocinnolines by a Japp-Klingemann Type Reaction

Pyrrolocinnoline derivatives were obtained by an unusual Japp-Klingemann reaction involving an intramolecular azadehalogenation on the pyrrole nucleus.Such an azadehalogenation represents the first example of Japp-Klingemann reaction in which the e

POLYCONDENSED NITROGEN HETEROCYCLES. PART XI. 1,3-DISUBSTITUTED 2-METHYLPYRROLOCINNOLINE AND 2-ACETYL-3-METHYLPYRROLOBENZOTRIAZINE

The diazotization of 1,3-disubstituted 2-methyl-5-(2-aminophenyl)pyrroles (2) and the intramolecular coupling reaction of the resulting diazonium salts lead to pyrrolobenzotriazine 4 when R = H.Compound 3d inhibited the germination of seeds
