The total synthesis of lepadiformine has been achieved in 10 steps and 15% overall yield from cyclohexanone. The amino-substituted quaternary carbon center is created through a radical carboazidation reaction. The tricyclic core of lepadiformine is built via an efficient hydrogenation process, involving reduction of the azide and intramolecular reductive amination of a ketone, followed by lactamization of the intermediate gamma-aminoester. The hydroxymethyl side chain is introduced according to a modified Takahata procedure after conversion of the lactam into a thiolactam.
