A novel visible-light-introduced reaction for the construction of oxindole derivatives via tandem radical cyclization of N-aryl acrylamides with diethyl bromomalonate has been developed. The reaction has been achieved in high yield under mild conditions by using Eosin Y as photocatalyst, which is cheap, easy to handle and environmentally friendly. It might provide a promising protocol for the synthesis of oxindole derivatives.

Key words: eosin Y, photoredox catalysis, oxindoles, radical cyclization
