A robust, click-chemistry-inspired procedure for radiolabeling of cyclic ureas was developed. This protocol, suitable for all carbon isotopes (11 C, 13 C, 14 C), is based on the direct functionalization of carbon dioxide: the universal building block for carbon radiolabeling. The strategy is operationally simple and reproducible in different radiochemistry centers, exhibits remarkably wide substrate
开发了一种强大的、受点击化学启发的环状脲放射性标记程序。该协议适用于所有碳同位素(11 C、13 C、14 C),基于二氧化碳的直接功能化:碳放射性标记的通用构建块。该策略操作简单,在不同的放射化学中心可重复,具有非常宽的底物范围和较短的反应时间,并且与之前报道的系统相比表现出优异的反应性。通过该程序,多种药物和未受保护的肽被高放射化学效率标记。
