2-Oxindole is a widely present skeletal structure in natural active products and drug molecules, and the radical cascade cyclization of N-arylacrylamide is the most effective method for synthesizing such compounds. Suitable free radical precursors can generate corresponding free radicals under the drive of light, electricity, or heat, thereby inducing a free radical cascade cyclization reaction of N-arylacrylamide to synthesize 2-oxindoles. Herein the research progress on the generation of free radicals induced by light, electricity, and heat in recent years and their application in the cascade cyclization of N-arylacrylamide to synthesize 2-oxindoles are systematically introduced.
Key words: photocatalysis; electrocatalysis; 2-oxindole; N-arylacrylamide
