Asymmetric allylation of carbonyl groups has been extensively studied because of the high versatility of enantiomerically enriched homoallylic alcohols.[1] There are four main methods for catalytic asymmetric carbonyl allylation: a) using allylmetal species (such as allyl tin, allyl silicon, and allyl boron reagents),[2] b) using the catalytic variant of the Nozaki–Hiyama reaction,[3] c) using reductive generation of nucleophilic π-allyl palladium from allylic ...
