convenient and efficient alternative to the classical Richman–Atkins methodology for obtaining PCTA and new derivatives is reported. The key macrocyclization step occurs in good yields as a result of a sodium template effect. The potentiality of lanthanide(III) complexes derived from these new PCTA ligands to act as paramagnetic contrastophores or luminophores is reported.
据报道,它是传统的Richman-Atkins方法获得PCTA和新衍生物的一种便捷有效的替代方法。由于钠模板效应,关键的大环化步骤以高收率发生。据报道,衍生自这些新的PCTA配体的镧系元素(III)可能用作顺磁性造影剂或发光体。
