An unprecedented nickel-catalyzed hydroarylative and hydroalkenylative cyclization of unsymmetrically substituted 1,6-dienes with organoboronic acid was developed by using MeOH as the hydrogen source and employing commercially available Ni(η-1,5-cyclooctadiene) as the catalyst. A series of biologically interesting cyclic products were afforded in moderate to excellent yields with high regio- and diastereoselectivities.
