7,8,9,14-hexahydrodibenz[d,g]azecines are known to be potent dopaminereceptor antagonists, whereas the corresponding rigid dibenzo[d,g]quinolizines are inactive. We built the scaffolds of dibenzo[c,g], [c,f] and [d,f]azecines and together with their ring closed, more rigid precursors, evaluated the affinities for the human D1–D5 receptors (radioligand binding) as well as the functionalities (calcium
