previously reported structures and a potential geometry fit with substrates, a new family of chiral dioxocyclam derivatives have been designed. The synthesis of those ligands was accomplished starting from l-proline and α-d-amino acids (converted to β-amino acids) with a key step of macrocyclization reaction of amino esters. All ligands were converted into neutral copper(II) complexes (amide groups underwent
基于对先前报道的结构的分析以及与底物的潜在几何结构,设计了新的手性二氧杂环丁烷衍生物家族。这些配体的合成是从l-脯氨酸和α-d-氨基酸(转化为β-氨基酸)开始的,这是氨基酯大环化反应的关键步骤。将所有配体转化成中性铜(II)配合物(在用乙酸铜(II)处理配体后使酰胺基脱质子化)。通过X射线分析证明,该配合物表现出其活性表面的所需形状。
