  日期：——

  direct C–H functionalization approach to access C3-alkylated 2-pyridone derivatives is reported. This study utilizes N-hydroxyphthalimide (NHPI) esters of various carboxylic acids as sources of alkyl radicals by reductive cleavage under photocatalytic reaction conditions. The carbon–carbon bond formation occurred site-selectively at C3 of 2-pyridone to give the desired products in moderate to good yields
