Stereoselectivity in ring-closing olefin metathesis (RCM) of tethered dihexenoyl derivatives

Abstract

Ring-closing olefin metatheses (RCM) of various tethered dihexenoyl derivatives were examined under various conditions. The E ∶ Z ratios of the resulting double bonds of the cyclic products were determined. The stereochemistry of the resulting olefins was influenced largely by the effects of the template used.
