Exocyclic alkene synthesis via stereoselective radical cyclizations
The stereoselectivity of radical cyclizations of stabilized radicals to alkynyl esters was investigated. In most cases, reactions mediated by tri(A7-butyl)tin hydride afforded predominantly E-exocyclic alkenes, whereas reactions mediated by tris(trimethylsilyl)silane afforded predominantly Z-exoc...
