Catenanes that are chiral owing to the relative orientation of their rings have always been referred to as ‘topologically chiral’. It is now shown that although in specific cases the stereochemistry is a topological property of the structure, the underlying stereogenic unit itself is not inherently topological in nature.

并非所有具有定向环的链烷都是拓扑手性的

由于环的相对方向而具有手性的链烷一直被称为“拓扑手性”。现在表明，虽然在特定情况下立体化学是结构的拓扑特性，但基础立体单元本身在本质上并不是固有的拓扑。
