Herein, a visible-light-induced umpolung strategy for reductive carboxylation of imines for synthesis of unnatural α-amino acids was disclosed. A reaction mechanism involving electron-donor–acceptor (EDA) complex formation between substrate and oxalate to furnish the desired products was proposed. Oxalic salt in situ generates CO2 radical anion (CO2•–) and carbon dioxide (CO2) as the key single-electron
在此,公开了用于合成非天然α-氨基酸的亚胺还原羧化的可见光诱导的反极性策略。提出了一种涉及底物和草酸盐之间形成电子供体-受体(EDA)络合物以提供所需产物的反应机制。草盐原位生成CO 2 自由基阴离子(CO 2 •– )和二氧化碳(CO 2 )作为关键单-在有或没有光催化剂的转化过程中分别使用电子还原剂和羰基(C1)源。
