organic cages which are formed by exploiting dynamiccovalentchemistry, such as boronic ester cages, imine cages, or disulfide cages, those with a fully carbonaceous backbone are rarer. With the exception of alkyne metathesis based approaches, the vast majority of hydrocarbon cages need to be synthesized by kinetically controlled bond formation. This strategy implies a multiple step synthesis and no
与通过利用动态共价化学形成的有机笼子(例如硼酸酯笼子,亚胺笼子或二硫键笼子)相比,具有完全碳质骨架的有机笼子更为罕见。除了基于炔烃复分解的方法外,绝大多数烃笼需要通过动力学控制的键形成来合成。这种策略意味着多步合成,并且在最后的大环化步骤中没有校正机制,这两者都是导致总收率低的原因。对于较小的笼子,固有的缺点并不总是很明显,而很少合成较大的笼子,其产量超过百分之几十分之一。本文介绍了一种将亚胺笼转化为烃笼的三步法。72 H 72 是20多年前FritzVögtle建议的未知笼子。

Interior decorating: A post‐synthetic method allows porousorganiccagecompounds to be prepared with functionalized interior cavities. The approach produces modified cagecompounds in quantitative yield and opens the possibility of preparing organic alloys with different functionality. The solution‐based technique shows the advantage of solubility, an inherent property of porous materials derived
