cyclophane presenting a bowl-shaped conformation, used as building block to construct cryptophane and hemicryptophane capsules. A method to synthesize new enantiopure CTV derivatives with an unprecedented spatial arrangement of their substituents, exhibiting C1 symmetry, is described. The absolute configuration was assigned by ECD spectroscopy coupled with modeling. A statistical model has allowed for optimization
环戊三烯(CTV)是一种呈碗状构象的大环环烷,用作构建色氨酸和半色氨酸胶囊的构件。描述了一种合成新的对映纯CTV衍生物的方法,该衍生物具有空前的取代基空间排列,表现出C 1对称性。绝对构型是通过ECD光谱法和建模分配的。统计模型允许优化C 1 CTV的比例,并且此方法的模块性也得到了强调。
