Аннотация: New synthetic approaches to fluorinated 3-phenyl-1,2,4-benzotriazines for biological testing have been elaborated. 1-(3,4-Difluorophenyl)-3,5-diphenylformazan (IVa) was synthesized via dinitriding of 3,4-difluoroaniline, followed by azo-addition of the resulting azobenzenediazonium chloride with acetaldehyde phenylhydrazone. 6,7-Difluoro-3-phenyl-1,2,4-benzotriazine (Va) was obtained via intramolecular cyclization of formazan IVa in the presence of BF3/AcOH complex. Monofluoro-substituted 6-R-7-fluoro-3-phenyl-1,2,4-benzotriazine derivatives (Vb-Vq) were prepared by substituting fluorine atom with alkoxides in 3,4-difluoronitrobenzene. Conditions for nucleophilic substitution of the second fluorine atom in benzotriazines V have been established. Fluorinated 3-phenyl-1,2,4-benzotriazines have been tested for antiviral and cytotoxic activity on Vero cell cultures and proved to be active against severe diseases caused by smallpox and some other pathogenic viruses. ??

Аннотация: A new approach for the synthesis of fluorinated 1H-quinazolin-4-ones and 4-substituted quinazolines has been developed. 6-Fluoro-1H-quinazolin-4-ones were obtained by intramolecular cyclization of fluorine-containing S-ethyl N-benzoylisothioureas. Nucleophilic substitution reactions at positions 2 and 7, as well as alkylation at 1-position of quinazolinones were investigated. In addition, the synthesis of fluorine-containing 4-aminoquinazolines was carried out.

    A simple one pot synthesis of condensed 1,2,4-triazines by using the tandem AN-SNipso and SNH-SNipso reactions [Text] / O. N. Chupakhin, G. L. Rusinov, D. G. Beresnev, V. N. Charushin, H. Neunhoeffer // Journal of Heterocyclic Chemistry. - 2001. - Т. 38, № 4. - P901-907

Аннотация: A new synthetic approach to condensed 1,2,4-triazines based on using the tandem AN-SNipso and SNH-SNipso reactions has been developed. 5-Methoxy-3-penyl-l,2,4 1,2,4-triazine and its N1-methyl quaternary salt were found to react with C,N-, C,O- and N,N?-bifunctional nucleophiles (m-phenylenediamine, resorcinol, semicarbazide and ureas) into triazacarbazoles, benzofuro[2,3-e][1,2,4]-triazines, and 6-azapurine derivatives. In all cases nucleophiles attack first the unsubstituted C-6 carbon of the triazine ring, while the final stage is replacement of the methoxy group affording cyclization products.
