Abstract:

Reactions of 2-aminopyridine and 2-amino-5-methylpyridine with 2,3,4,5-tetrafluorobenzoyl chloride afforded N,N'-diaroylpyridinium salts, which were converted into 6H-pyrido{[}1,2-a]quinazolin-6-ones by refluxing in toluene in the presence of triethylamine. The angular structure of the tricyclic derivatives obtained was confirmed by F-19 and C-13 NMR spectroscopy and 2D heteronuclear HetCOR and HMBC experiments.
