A synthesis of the alkaloid pseudoconhydrine and its epimer has been achieved using tandem hydroformylation–condensation to form the six-membered ring and stereoselective dihydroxylation to introduce oxygenation. The stereoselectivity of dihydroxylation can be explained by lipophilic and electrostatic effects, supported by DFT calculations. The alkaloids can be obtained either by regioselective dehydroxylation
