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]
通过使用2 - 5摩尔%的手性钼配合物进行不对称闭环复分解反应(ARCM),可高效合成碳环胺,对映体过量率高达93%。文中给出了一个示例,即原位制备催化剂(无需分离催化剂)以得到无法通过其他方法制备的仲胺。[反应:见正文]
