Highly selective olefin-assisted palladium-catalyzed oxidative carbocyclization via remote olefin insertion

Abstract

A highly selective olefin-assisted palladium-catalyzed oxidative carbocyclization via remote olefin insertion to afford cyclohexenes has been developed. It was shown that the assisting olefin moiety was indispensable for the formation of the cyclohexene product. Furthermore, preliminary studies on chiral anion-induced asymmetrical carbocyclization–borylation of enallenes have been carried out.
