The enantioselective alkylation of α,β-unsaturated aldehydes with stabilized carbocations as electrophiles via the activation as dienamine intermediates is described. This unique application of dienamine catalysis allows for the first enantioselective γ-alkylation of linear α,β-unsubstituted enals.
描述了通过活化为二烯胺中间体,以稳定的碳阳离子作为亲电子体的α,β-不饱和醛的对映选择性烷基化。二烯胺催化的这种独特应用使线性α,β-未取代的烯醛首次对映选择性γ-烷基化。
