extension of previous investigations on synthesis and dopamineautoreceptoractivity of bicyclic ergoline analogues the tricyclic azaergoline analogues 9a and 9b were synthesized. Furthermore, the geometry of the aromatic β‐ethylamine moiety of 9a,b was modified by stereoselective construction of the cycloheptenyl fused pyrazolopyridine derivative 7 and the aminomethyl substituted tricycle 10.
