The sequential use of Cu-catalyzed asymmetric allylic alkylation, olefin cross-metathesis, and Ir-catalyzed asymmetric allylic amination allows the concise, stereodivergent synthesis of complex chiral amines with complete regiocontrol and good diastereoselectivity, exemplified by the synthesis of a pair of diastereoisomeric unnatural branched amino acid derivatives.
顺序使用Cu催化的不对称烯丙基烷基化,烯烃交叉复分解和Ir催化的不对称烯丙基胺化可以实现简明,立体发散的复杂手性胺的合成,具有完全的区域控制性和良好的非对映选择性,以合成一对非对映异构体非天然为例支链氨基酸衍生物。
