Two mesitylene-bridged hexaazamacrobicyclic ligands 1 and 2 were prepared by a three-step process from available 2,4,6-tris(bromomethyl)mesitylene (9) and N, N'-di-p-tosylethylenediamine and N, N'-di-p-tosyl-1,3-diaminopropane. First, mono-BOC-protected ditosylamines 5 and 6 were prepared by treating the two diamines with BOC-O-BOC. These mono-BOC-protected diamines were treated with the tris(bromomethyl)-mesitylene
两个均三甲苯-桥连配体hexaazamacrobicyclic 1和2通过一个三步过程从可用2,4,6-三(溴甲基)均三甲苯(制备9)和N,N“ -二p -tosylethylenediamine和N,N” -二-对甲苯磺酰基-1,3-二氨基丙烷。首先,通过用BOC-O-BOC处理两个二胺来制备单-BOC保护的二甲苯磺胺5和6。将这些单BOC保护的二胺用三(溴甲基)-亚甲基三甲苯处理,然后脱保护得到2,4,6-三(2,5-二甲苯基-2,5-二氮杂戊基)亚甲基(3)及其2, 6-二氮杂己基类似物4。后者的中间体用三(溴甲基)均三甲苯处理,得到均三甲苯间桥连的六氮杂双环。此三步综合替代了所报告的九步过程。
