sp3 Hybridized electrophiles, never before used in the organomediated MoritaâBaylisâHillman reaction, now facilitate the formation of five- and six-membered enone cycloalkylation products.

From the initial development of a homologous Morita–Baylis–Hillman reaction utilizing epoxides as electrophiles, the method was expanded to enable the exclusively organocatalyzed intramolecular allylation of enones and to develop the intramolecular MBH-type alkylation of activated alkenes. We successfully utilized both enones and unsaturated thioesters as the activated alkene component. This work,
