Two new cucurbituril members, one containing two equivalent cavities and the other having an active secondary amine group, were synthesized by condensation of propanediurea (2,4,6,8-tetraazabicyclo[3.3.1]nonane-3,7-dione) with formaldehyde. These two macrocycles exhibit excellent thermal stability, and their structures were confirmed by single-crystal X-ray diffraction, 1H NMR spectroscopy, and high-resolution mass spectrometry.

两种基于丙二脲的葫芦脲类似物：Bis-ns-TD[8] 和 NH-ns-TD[4]
通过丙二脲（2,4,6,8-四氮杂双环[3.3.1]壬烷-3,7-二酮）与甲醛。这两个大环表现出优异的热稳定性，其结构已通过单晶 X 射线衍射、1H NMR 光谱和高分辨率质谱证实。
