A D(3)-symmetric knotted cyclophane, with a subgraph of trefoil topology, was synthesized by cyclization of a D(3)-symmetric scaffold. Control of configuration at the three metal-based stereocenters arises from a bascule/pivot mechanism.
一种 D(3)-对称的纽结环芳烷,具有三叶形拓扑的子图,通过 D(3)-对称支架的环化合成。三个基于金属的立体中心的构型控制源于枢轴/枢轴机制。
