Short enantio- and diastereoselective syntheses of the decahydroquinoline alkaloids cis- (pumiliotoxin C) and trans-195A are presented. Key steps are an enantioselective iridium-catalyzed allylic amination, a Suzuki–Miyaura coupling, a catalyst-controlled copper-catalyzed 1,4-addition, and a reductive amination.
