modified cyclic peptides, bearing dipicolylamine side chains for metal complexation and subsequent anion binding studies. Two approaches to the cyclic peptides were investigated. Initially, a stepwise approach was employed, involving solid-phase assembly of oxazole-based building blocks, followed by solution-phase macrolactamisation of the resulting linear precursor. The alternative strategy involved the
我们在这里报告设计和合成的新型骨架修饰环肽家族,该环肽带有二聚烯丙基胺侧链,用于金属络合和随后的阴离子结合研究。研究了环肽的两种方法。最初,采用逐步方法,其中包括以固相组装恶唑基结构单元,然后对所得线性前体进行溶液相大内酰胺化。替代策略涉及在溶液相中形成线性双恶唑片段,然后进行环二聚反应。这些受体的锌(II)配合物选择性地结合磷酸氢根上的二磷酸根离子和三磷酸根离子。
