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.
investigated(II)二碘化物介导的简单双烯-烯酸酯和-烯酸酯在THF / MeOH中的分子内环二聚。以合成上有用的产率获得包括立体定义的顺式-双环[3.3.0]辛烷和反式-双环[4.3.0]壬烷的螺环和精细的多环产物。
