The oxindole scaffold is a highly valuable structural motif and their synthesis research is of great significance. N-arylacrylamides have been the important raw materials for the synthesis of oxindoles, because of their high reactivity, cheap and ready availability. In recent years, photo-mediated N-arylacrylamides engaged in radical cyclization reactions have made a great advance, which has received considerable attention. In this article, the research progress is systematically summarized, including radical coupling and cyclization reactions of N-arylacrylamides with alkyl, fluorinated alkyl, acyl, sulfonyl radical precursors, and among others. These methods bearing advantages and disadvantages, substrate scope, and mechanisms were discussed.
