Abstract
The structure of 7-meth-oxy-penta-cyclo-[5.4.0.0.0.0]undecane-8,11-dione, CHO, at 150 K has monoclinic (2/) symmetry. The penta-cyclo-undecane cage compound is composed of four five-membered rings, a planar four-membered ring and a six-membered ring in a boat conformation fused into a closed strained-cage framework. All of the five-membered rings adopt an envelope conformation.
摘要
7-甲氧基-五环-[5.4.0.0.0.0]十一烷-8,11-二酮（CHO）在150 K时的结构具有单斜（2/）对称性。该五环十一烷笼状化合物由四个五元环、一个平面四元环和一个呈船式构象的六元环稠合形成一个封闭的张力笼状骨架。所有五元环均呈信封式构象。
