and bishomododecahedral cage molecules with one and two OCO (OCH2) linkers installed into the parent pentagonal framework and featuring diverse functionalization patterns have been made available from pagodane precursors via highly expeditious synthetic sequences. The enforced geometrical changes with respect to molecular curvature, olefinic pyramidalization, transannular π,π-distance as well as to the
从宝塔丹前体通过快速合成序列可得到具有一个和两个OCO(OCH 2)连接基的同-和双-十二面体的笼状分子,该连接体安装在母体五边形框架中,并且具有多种功能化模式。关于分子曲率,烯属锥体化,跨环的π,π距离以及
化学反应性(特别是不饱和同十二面体的
化学反应性)的强制性几何变化通常与基于计算(MM2)的预期高度吻合。在可观的
金字塔形的单十二碳八烯骨架40中,不平行的π键为约1。2.9(3.1)Å[Φ= ca. 20(32)°,MM2],在双同十二碳八烯骨架55中syn -periplanarπ键相距2.81Å(Φ= 18.2°,X射线晶体结构)。
