One-pot Annulation to Tricyclo3,8>undecane-2,6-diones by Sequential Three-fold Michael Reactions. A Formal Synthesis of (+/-)-Seychellene

Lewis acid-assisted triple Michael reactions yield tricyclo3,8>undecane-2,6-dione derivatives from the trimethylsilyl enol ethers of cyclohex-2-enones and divinyl ketone.The application of this reaction allowed a formal synthesis of (+/-)-seychellene.

Direct stereoselective total synthesis of (±)-seychellene

A very short total synthesis of seychellene is described in which the tricyclic ring system is prepared by a cycloaddition-Michael reaction approach.
