title: Synthesis of new linearly annulated tricycles as rigid dopamine congeners.
abstract: A simple synthetic route that leads to three isosters of octahydrobenzo[g]quinolines (IA), in which the carbon atom in 4-position is replaced by an oxygen, a sulfur or a nitrogen atom, to give hexahydronaphth-[1,4]oxazine (VIII a) and -[1,4]thiazine (VIII b), and octahydrobenzo[g]quinoxaline (VIII c) respectively, is here reported. These compounds can be considered as new structural models of dopamine agonists.
