α-oxocarboxylic acids by using a readily accessible organic pyrimidopteridine photoredox catalyst under ultraviolet-A (UV-A) light irradiation. These reactive acyl radicals were smoothly added to olefins such as styrenes and diverse Michael acceptors, with the assistance of H2O/D2O as hydrogen donors, enabling easy access to a diverse range of ketones/β-deuterio ketones. A wide range of α-oxocarboxylic
在紫外 A (UV-A) 光照射下,使用易于获得的有机嘧啶蝶啶光氧化还原催化剂,通过 α-氧代羧酸的脱羧生成酰基自由基。在H 2 O/D 2 O作为氢供体的帮助下,这些反应性酰基顺利地加成到苯乙烯等烯烃和各种迈克尔受体上,从而能够轻松获得各种酮/β-氘酮。多种α-氧代羧酸都与该反应兼容,这显示出可靠、原子经济且环保的方案。此外,还介绍了合成后的多样化和应用。
