with hydrogen atom transfer to enable C–H alkylation of quinoxalin-2(1H)-ones with feedstock aldehydes, amides, alcohols, ethers, or cycloalkanes. This reaction occurred under environmentally benign and external oxidant-free reaction conditions, providing a general and sustainable access to various C3-alkylated quinoxalinone derivatives with broad substituent diversity and good functional group compatibility
描述了一种温和的方法,将有机光氧化还原催化与氢原子转移相结合,使 quioxalin-2(1 H )-ones 与原料醛、酰胺、醇、醚或环烷烃发生 C–H 烷基化。该反应发生在环境友好且无外部氧化剂的反应条件下,为获得具有广泛取代基多样性和良好官能团相容性的各种 C3-烷基化喹喔啉酮衍生物提供了普遍和可持续的途径。
