Get selective! Enantioselective allylation of ketimines derived from isatins by using chiral 1,3‐bis(imidazolin‐2‐yl)benzene (Phebim)–PdII complexes afforded products with good enantioselectivity (see scheme). The reaction was applied to a wide variety of ketimines. The obtained product can be converted to homoallylic amines and a spirocyclic amine without the loss of enantiopurity.
变得有选择性!通过使用手性1,3-双(咪唑啉-2-基)苯(Phebim)-Pd II复合物,对源自靛红的酮亚胺进行对映选择性烯丙基化,可得到具有良好对映选择性的产品(参见方案)。该反应被应用于各种各样的酮亚胺。所获得的产物可以转化为均烯丙基胺和螺环胺而不会损失对映体纯度。
