1,4,7,10-Tetraazacyclododecane reacts regioselectively in acid solution with several chloroformates to give 1,7-diprotected derivatives which could be alkylated and deprotected to afford 1,7-disubstituted 1,4,7,10-tetraazacyclododecanes.
1,4,7,10-四氮杂环十二烷在酸性溶液中区域选择性地与多种氯甲酸酯反应,生成1,7-二保护衍生物,这些衍生物可以被烷基化并脱保护,从而得到1,7-二取代的1,4,7,10-四氮杂环十二烷。
