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

Polysubstituted pyridine derivatives were synthesized through economical one-pot multicomponent reactions of different α,β-unsaturated ketones, malononitrile, and ethanol or methanol in the presence of Amberlite IRA-400 (OH−) at room temperature. The catalyst is recyclable several times without substantial loss of activity. Other valuable features include the wide range of functional group tolerance
