The use of monodentate chiral spiro phosphoramidite ligands enables a highly enantioselective nickel-catalyzed intramolecular hydroalkenylation of easily accessible N- or O-tethered 1,6-dienes to provide very useful six-membered N- and O-heterocycles with high regioselectivity as well as excellent stereoselectivity under mild reaction conditions.
