new poly-azamacrocycles, valuable precursors of bifunctional chelating agents with applications in nuclear medicine, is reported. The desired functional group was introduced onto the macro-cycle backbone during the cyclization step, thus avoiding the tedious preparation of a C-functionalized synthon. The regioselective reaction of macrocycles bearing an aminomethyl pendant arm with aldehydes is also
报道了一种用于制备新型聚氮杂大环化合物的强大合成路线,该化合物是可用于核医学的双功能螯合剂的宝贵前体。在环化步骤中,所需的官能团被引入到大环骨架上,从而避免了繁琐的 C 官能化合成子的制备。还描述了带有氨基甲基悬臂的大环与醛的区域选择性反应。
