    名称:
    Rhodium-Catalyzed Vinylcyclopropanation/Cyclopentenation of Strained Alkenes via a Sequential Carborhodation Process
    摘要:
    A rhodium-catalyzed reaction of dienylboronate esters with alkenes is described. Strained bicyclic alkenes show the highest reactivity toward the rhodium-catalyzed addition of the dienylboronate esters. Depending on the substitution pattern of dienylboronate esters, an intramolecular 1,6- or 1,4-addition mechanism may be operative, affording carbocycles containing a vinylcyclopropane or cyclopentene moiety.
