The double selective synthetic approach is proposed for easy preparation of asymmetrically N-substituted derivatives of 1,4,7-triazacyclononane (tacn, [9]aneN3) with the same or different pendant arms. The synthetic routes simplify the synthesis of “tacn” ligands for functionalization of other carboxy terminated molecules/supports and also facilitate access to azamacrocycle functionalized self-assembled
提出了双选择性合成方法,以易于制备具有相同或不同侧链的1,4,7-三氮杂环壬烷(tacn,[9] aneN 3)的不对称N-取代的衍生物。合成途径简化了“ tacn”配体的合成,以使其他羧基封端的分子/支持物官能化,并且还促进了氮杂大环官能化的自组装单层(SAMs)或纳米模式的获得,以进行特异性和稳定的组氨酸标记的蛋白质固定。
