A convenient synthesis of a bifunctional derivative of the ligand NOTA is described. The synthesis offers advantages over current literature methods for making similar molecules by starting with the easily prepared ortho-amide of 1,4,7-triazacyclanonane which can be sequentially alkylated to provide a bifunctional NOTA derivative in 9% yield overall. The replacement of preparative HPLC with simple
描述了配体NOTA的双功能衍生物的方便合成。相对于现有文献方法而言,该合成方法具有优势,可通过容易制备的1,4,7-三叠氮基壬烷的邻酰胺开始制备类似的分子,该邻酰胺可以依次烷基化以提供双官能NOTA衍生物,总产率为9%。用简单的离子交换色谱法代替制备型HPLC可提供适合临床应用的分析纯配体。
