ALLYLIC ALKYLATION OF INDOLES WITH BUTADIENE PROMOTED BY PALLADIUM CATALYST AND TREETHYLBORANE

摘要

Triethylborane promotes the Pd-catalyzed allylic alkylation of a wide variety of indoles with 1,3-butadiene to provide C3-octadienylindoles and C3-bis(octadienyl)indolenines in good to excellent yields under mild conditions.
