Pyrrolo indazoles

Nitrogen Systems.—A review on the synthesis of pyrrolo[l,2-a]indoles (754) and related systems has appeared. Treatment of azobenzene (755) with 2,6-dimethylphenyl isocyanide (756) in the presence of dicobalt octacarbonyl yields a mixture of the imino-indazoline (757) and the indazolo-indazole (758)." Heating 5-amino-l-o-chlorophenyl-pyrazoles (759 R = CN or C02Et) in DMF in the presence of copper oxide yields the pyrazolo-benzimidazoles (760)." ... [Pg.81]
