Dynamic covalent chemistry is an effective technique for the preparation of complex organic compounds. We succeeded in synthesizing a cage-shaped compound through the aggregation of two types of functional molecules. More specifically, a tris-imine 5 was quantitatively obtained by reacting a C₃-symmetric trialdehyde 1 with a triamine 4 in acetonitrile in the presence of a trifluoroacetic acid catalyst. We also achieved the synthesis of the corresponding triamine 9 and the acetylated derivative 10 through reduction of the tris-imine CN double bonds and subsequent acetylation.

通过三醛和三胺之间的动态共价键形成合成C ₃对称的三亚胺

动态共价化学是制备复杂有机化合物的有效技术。我们通过两种功能分子的聚集成功地合成了笼状化合物。更具体地，通过在三氟乙酸催化剂存在下使C ₃对称的三醛1与三胺4在乙腈中反应来定量获得三亚胺5。通过还原三亚胺C N双键并随后进行乙酰化，我们还实现了相应的三胺9和乙酰化衍生物10的合成。
