reaction was developed for direct amidation of aldehydes under metal-free conditions employing molecular oxygen as the oxidant. 9-Aminofluorene derivatives acted as pyridoxamine-5′-phosphate equivalents for efficient, chemoselective, and operationally simple amine-transfer oxygenation reaction. Unprecedented RNH transfer involving secondary amine to produce secondary amides was achieved. In the presence
开发了一种基于多米诺胺胺氧化反应的概念上新颖的仿生策略,用于在无金属条件下使用分子氧作为氧化剂对醛进行直接酰胺化。9-氨基芴衍生物可作为吡ido胺-5'-磷酸盐的等效物,用于高效,化学选择性和操作简单的胺转移加氧反应。实现了前所未有的RNH转移,涉及仲胺生成仲酰胺。在存在18 Ò 2,18 O形酰胺具有优异的(95%)的同位素纯度形成。
