Small libraries of 3,5-unsubstituted 4-substituted-6-aryl-3,4-dihydropyridin-2(1H)-ones derivatives were synthesized from the condensation-products of aldehydes with Meldrum's acid, aromatic ketones and ammonium acetate using acetic acid as energy transferring-agent under microwave irradiation without catalyst. This method has the advantages of excellent yields (65-90%), short reaction time (5-10 min)
由醛与梅德鲁姆酸,芳香族酮和乙酸铵的缩合产物,用乙酸合成了3,5-未取代的4-取代的6-取代的6-芳基-3,4-二氢吡啶-2-2 (1 H)-ones衍生物的小型文库在没有催化剂的情况下,微波辐射下的酸作为能量转移剂 该方法的优点是收率优异(65-90%),反应时间短(5-10分钟),并且对环境友好。它旨在为生物医学筛选提供一系列潜在的生物活性化合物。
