The synthesis of two new polyamine macrocycles, each bearing the 1,1′-bis(2-phenol) group as an integral part of the cyclic framework, is reported. The ligands were obtained by template reactions using a cadmium(II) complex of the suitable polyamine condensed with 3,3′-diformyl-1,1′-bis(2-phenol), followed by selective reduction of the two imine bonds and demetallation in acidic medium.
报道了两个新的多胺大环的合成,每个大环带有1,1'-双(2-苯酚)基团作为环状骨架的组成部分。通过使用合适的多胺的镉(II)配合物与3,3'-二甲酰基-1,1'-双(2-苯酚)缩合的模板反应获得配体,然后选择性还原两个亚胺键并脱金属在酸性介质中。
