The affinities of tetrahydroprotoberberines for dopaminereceptors dramatically decrease after cleaving the central C‐N bond to the analogous ten‐membered dibenzo[c,g]azecines [1]. In the present work, we also synthesized eleven‐membered homologues of these heterocycles and measured the affinities of the resulting dibenzazaundecenes and their underlying homoberberines for human dopaminereceptors as
