In this paper, 21 naphthalene-chalcone derivatives were synthesized and their biologicaleffects were evaluated. The results showed that compounds 2a–2u displayed clear antidepressant activity at 30 mg/kg in the forced swimming test. Compounds 2h, 2o, 2t, and 2u exhibited a good antidepressant effect in the forced swimming test and tail suspension test at 30 mg/kg. Compounds 2h, 2o, 2t, and 2u but

catalyzed three-component synthesis of π-conjugated tetracyclic thiochromeno-quinolinone and thiochromeno-thioflavone was established via oxidative double hetero Michael additionusing in situ generated nucleophiles. Xanthate plays a dual role as an odourless sulfur source and a chemoselective reducing agent. The in situ formed iodine plays a crucial role in the oxidation step.
