Carbocyclic amines are synthesized efficiently in up to 93% ee by asymmetric ring-closing metathesis (ARCM) with 2-5 mol % chiral Mo complexes. An example is provided where the catalyst is prepared in situ (catalyst isolation not needed) to afford secondary amines that cannot be prepared by alternative methods. [reaction: see text]
通过具有2-5 mol%手性Mo络合物的不对称闭环复分解(ARCM),可以最高达93%ee高效地合成碳环胺。提供了一个实例,其中就地制备催化剂(不需要分离催化剂)以提供不能通过替代方法制备的仲胺。[反应:看文字]
