A diastereoselective approach to 2,5-substituted decahydroquinolines by zirconium-mediated cyclization of unsaturated α,α′- disubstituted piperidines II is described. The required piperidines could be obtained from secondary sulfonamides III via ruthenium-catalyzed ring-rearrangement metathesis (RRM) in high yields. Racemic trans-195A and 2-epi-trans-195A were synthesized in 8 steps starting with butyraldehyde and cyclohex-2-enol.

A biomimetic approach towards the synthesis of pumiliotoxin C has been developed.The key transformation of enamine equivalent 8 to 9 was catalyzed by contact with alumina.Cyclized intermediate 9 was then reduced stereospecifically to the trans decahydroqu
