Herein, we introduce an efficient and straightforward strategy for the selective C-H esterification alkylation of quinoxalin-2(1H)-ones with aldehydes. A key feature our study is ability to perform both using different types The reaction system highly compatible a range aldehydes, yielding C3-esterified C3-alkylated products in moderate-to-good yields. applicability this approach further enhanced by its scalability through continuous-flow synthesis, late-stage modification significant molecules, product derivatization. Our mechanistic investigations reveal radical relay mechanism, triggered hydrogen atom transfer process.
