Synthesis of 6-acyl-5,8-quinolinediols by photo-Friedel–Crafts acylation using sunlight

Abstract Synthesis of acyl-5,8-quinolinediols using sunlight was investigated. Photo-Friedel–Crafts acylation of quinoline-5,8-dione and aldehyde afforded the corresponding 6-acyl-5,8-quinolinediols regioselectively in moderate to good yields. The compounds have a variety of potential applications.
