Abstract

A novel nitration and oxidation reaction sequence of 2-acetyl-1-naphthol benzoylhydrazones with CAN is presented. There is strong indication that nitration precedes an oxidative rearrangement to 1,2-diacyl-4- nitronaphthalenes or oxidative electrocyclisation to 3-methyl-5-nitronaphtho[2,1-d]isoxazole. Condensation of 1,2-diacyl-4-nitronaphthalenes with hydrazine hydrate yields 1,4-disubstituted benzo[f]phthalazines. [ABSTRACT FROM AUTHOR]

Abstract

A series of novel 3-azolylpyrazolo[5,1-c][1,2,4]triazines was synthesized by reaction of 3-substituted pyrazole-5-diazonium salts with β-azolyl enamines in an efficient fashion. The structures of the compounds prepared were characterized by NMR spectroscopy, massspectrometry, elemental and X-ray diffraction analyses. Plausible mechanisms were formulated.
