  • Title: Formal synthesis of (+/-)-guanacastepene A: a tandem ring-closing metathesis approach.
    Author: Boyer FD, Hanna I, Ricard L.
    Journal: Org Lett; 2004 May 27; 6(11):1817-20. PubMed ID: 15151422.
    Abstract:
    A concise route to a key intermediate in the total synthesis of guanacastepene A is described. The main features include the simultaneous construction of the seven- and six-membered rings, using a tandem ring-closing metathesis and a stereoselective introduction of the oxygenated function at the C5 position.
