Abstract :
Samarium(II) diiodide-mediated intramolecular cyclodimerisation of simple bis-enones and -enoates in THF/MeOH has been investigated. Spirocyclic and elaborated polycyclic products, including stereodefined cis-bicyclo[3.3.0]octane and trans-bicyclo[4.3.0]nonanes, are obtained in synthetically useful yield.
