以La 3+（核金属）和Zn 2+（壳金属）为新型核/壳模板，通过二醛2与二胺3的[3 + 3]缩合反应定量获得了36元大环六肟，但在没有金属离子的情况下产率很低。高产率可归因于有效地形成二醛2、Zn 2+和La 3+的3：3：1络合物，这容易得到保持Zn 3La核/壳四核簇结构的大环。
A 36-membered macrocyclic hexaoxime was quantitatively obtained by [3 + 3] condensation of dialdehyde 2 with diamine 3 using La3+ (core metal) and Zn2+ (shell metal) as a novel core/shell template, while the yield was very low in the absence of the metal ions. The high yield can be attributed to the efficient formation of a 3:3:1 complex of dialdehyde 2, Zn2+, and La3+, which readily gives the macrocycle keeping the Zn3La core/shell tetranuclear cluster structure.
