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
取代的吡啶衍生物是通过在的Amberlite IRA-400(OH的存在下不同的α,β不饱和酮,丙二腈和乙醇或甲醇的经济一锅多组分反应合成-在室温下)。该催化剂可循环使用几次,而活性没有实质损失。其他有价值的功能包括宽泛的官能团耐受性,简单的后处理步骤,易于清洁的合成以及在温和条件下的优异收率。
