An efficient method for the synthesis of azabicyclo[5.1.0]octenes through cycloisomerization of nitrogen-tethered 1,7-enynes catalyzed by [IrCp*Cl2]2 was developed. With appropriately designed substrates, this method could be easily employed to generate complex fused ringsystems such as [6-6-3-7], [5-6-3-7], [7-6-3-7], and [8-6-3-7] ringsystems, which enriches the diversity of the cyclopropane-fused
