Mechanical stereochemistry arises when the interlocking of stereochemically trivial covalent subcomponents results in a stereochemically complex object. Although this general concept was identified in 1961, the stereochemical description of these molecules is still under development to the extent that new forms of mechanical stereochemistry are still being identified. Here, we present a simple analysis of rotaxane and catenane stereochemistry that allowed us to identify the final missing simple mechanical stereogenic unit, an overlooked form of rotaxane geometric isomerism, and demonstrate its stereoselective synthesis.

[2]轮烷的最终立体单元：2 型几何异构体

当立体化学上平凡的共价子成分联锁产生立体化学复杂的物体时，就会产生机械立体化学。尽管这个一般概念是在 1961 年确定的，但这些分子的立体化学描述仍在发展中，新形式的机械立体化学仍在确定中。在这里，我们对轮烷和索烷立体化学进行了简单分析，使我们能够识别最终缺失的简单机械立体异构单元（轮烷几何异构体的一种被忽视的形式），并证明其立体选择性合成。
