Herein, we report a concise asymmetric totalsynthesis of isopavine alkaloids, which feature a special azabicyclo[3.2.2]nonane tetracyclic skeleton. The key steps include iridium-catalyzed asymmetric hydrogenation of unsaturated carboxylic acids, Curtius rearrangement, and Eschweiler–Clarke methylation, which enable an enantioselective approach to isopavine alkaloids in 6–7 linear steps. Furthermore
