A new ethylidene menthane-based chiral π-allylpalladium complex catalyzes the asymmetric allylation of various imines with allyltributylstannane and 1 equiv. of water to give chiral homoallylamines in good yields and enantioselectivities. The reaction was carried out essentially under neutral conditions and displayed a good transfer of chiral information from the menthane skeleton through the formation
一种新的基于亚乙基薄荷烷的手性 π-烯丙基钯配合物催化各种亚胺与烯丙基三丁基锡烷和 1 当量的不对称烯丙基化。水以良好的产率和对映选择性得到手性高烯丙胺。该反应基本上在中性条件下进行,并通过双(π-烯丙基钯)物种的形成显示了从薄荷烷骨架良好的手性信息转移。这是基于薄荷烷的手性双(π-烯丙基钯)催化的第一个例子。
