摘要：

Diazotization of 2-acetylenic derivatives of 1-aminoanthraquinone followed by intramolecular cyclization leads to the formation is good yields of 1H-3-acyl- or 1H-3-(1,1-dichloroalkyl)naphtho[2,3-g]indazole-6,11-diones, rather than 3-substituted 4-hydroxynahtho[2,3-h]cinnoline-7,1 2-diones, the normal Richter synthesis products.
