Palladium-promoted alkylation of alkenes using chiral sulfoxide-containing carbanions and chiral lithiated oxazolines results in asymmetric induction (AI) ranging from 3–5% (1,5 induction), 20–40% (1,3 induction) to 44–52% (1,4 induction). No general trend allowing predictions of results was found. With 1-hexene, attack at C(1) is almost exclusive but propene gives a mixture of attack at C(1) and C(2)
使用含手性亚砜的碳负离子和手性锂化的恶唑啉,钯促进烯烃的烷基化导致不对称诱导(AI)范围为3–5%(1.5诱导),20–40%(1,3诱导)至44–52 %(1,4感应)。没有发现可以预测结果的一般趋势。使用1-己烯时,几乎不排除对C(1)的进攻,但丙烯会同时对C(1)和C(2)进行进攻。手性配体与丙二酸根阴离子一起使用也会导致一些不对称诱导(约20%)。
