developed for the rapid assembly of anti-homoallylic alcohols with high levels of regioselectivities (>20:1), diastereoselectivities (up to >20:1), and yields (up to 91%). The allylation was realized through a crucial π-allylnickel intermediate, which was obtained via insertion of allenes with a Ni–H intermediate. Moreover, γ,γ-disubstituted homoallylicalcohols with a quaternary stereocenter can also be prepared
