A D3-symmetric knotted cyclophane, with a subgraph of trefoil topology, was synthesized by cyclization of a D3-symmetric scaffold. Control of configuration at the three metal-based stereocenters arises from a bascule/pivot mechanism.
通过环化 D3 对称支架,合成了具有三叶形拓扑子图的 D3 对称结环烷。三个基于
金属的立体中心的构型控制是通过基底/枢轴机制实现的。
