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