Reactivity insight into reductive coupling and aldol cyclization of chalcones by visible light photocatalysis.
The reductive coupling and cyclization of chalcones to generate cyclopentanol derivatives in up to 84% yield by visible light photoredox catalysis is described. This reaction involves radical anion homocoupling, monoprotonation, and intramolecular cyclization cascade.
