An efficient and sustainable visible light-promoted cascade radical cyclization of α-oxocarboxylic acids with o-(allyloxy)arylaldehydes towards the construction of 1,4-diketone containing chromanone derivatives has been developed. The reaction occurred under mild reactions, e.g. room temperature, blue LED irradiation, photoredox catalyst free, and provided the final heterocycles in moderate to good yields.

Key words: visible light, 4-chromanone, radical, cascade reaction
