In this paper we report the synthesis of new azabicycloalkane scaffolds, which could be exploited to obtain cRGD-based bioconjugates that may find promising application for targeted drug delivery, theranostic, and general cancer-cell labeling. By exploiting a Hosomi–Sakurai intramolecular allylation reaction we efficiently converted a silylated aldehyde precursor into 7,5-fused lactam scaffolds endowed
在本文中,我们报告了新的氮杂双环烷烃支架的合成,该支架可用于获得基于 cRGD 的生物缀合物,这些生物缀合物可能会在靶向药物递送、治疗诊断和一般癌细胞标记中找到有希望的应用。通过利用 Hosomi-Sakurai 分子内烯丙基化反应,我们有效地将甲硅烷基化醛前体转化为具有环外双键的 7,5-稠合内酰胺支架。乙烯基官能团的存在应该能够结合生物活性化合物以选择性地将它们携带到肿瘤部位。优化的合成顺序允许在几个步骤中以克级规模制备目标支架,并且从容易获得的材料中获得 39% 的良好总产率。
