Di- and triphenyldibenzoylpyridines (1) were prepared by the condensation reaction of 3,4-dibenzoyl-2,5-diphenylthiophene (2) with methylamine derivatives 3 and by subsequent oxidative ring cleavage of the resultant thienopyridines 4.The reaction of 1 with 3 afforded polyphenyl-2,6- (5) and -2,7-naphthyridines (6).
