Lycoperine A was synthesized through a highly convergent route in which a double alkylation of 2,6-dicyano-N-benzylpiperidine with the octahydroquinoline moiety gave the lycoperine skeleton. The octahydroquinoline was prepared by a desymmetrization reaction of 5-methylcyclohexane-1,3-dione. Hydrolysis, reductive amination and cyclization gave lycoperine A in 13 steps and 3% overall yield. The absolute configuration of lycoperine A was assigned as 6R, 6′R, 8R, 8′R, 13S, 17R.
