摘要：

Two new macropolycycles with large cavities, 2 and 3, were isolated in addition to known cryptand amide 1 following the high-dilution reaction of isophthaloyl dichloride and 1,10-diaza-18-crown-6 in toluene. Electrospray ionization mass spectrometry (ESI-MS) was applied for analysis and characterization of the reaction mixture of 1, 2, 3, and higher derivatives and the corresponding pure products as monocharged 1:1 complexes with sodium ion. Macrotricyclic amide 2 was reduced with borane to give cryptand 6. Structures of all mentioned compounds were supported by H-1 NMR, and 6 was also confirmed by X-ray crystallography.
