Abstract The reaction of trifold protected cyclen with fluorinated dinitroarenes yields aryl‐substituted or aryl‐bridged cyclen derivatives in good yield. The two arene nitro groups, necessary for the nucleophilic aromatic substitution, are subsequently selectively reduced to amines and further functionalized by amide formation. As an example, a cyclen derivative bearing a heterocyclic oligoamide with
摘要 三重保护的环烯与氟化二硝基芳烃反应以良好的收率得到芳基取代或芳基桥连的环烯衍生物。亲核芳族取代所必需的两个芳烃硝基随后被选择性还原为胺并通过酰胺形成进一步官能化。例如,制备了带有具有潜在 DNA 结合能力的杂环寡酰胺的 Cyclen 衍生物。
