Novel proline-catalyzed multicomponent reactions (MCRs) for the synthesis of fused pyrrolo[3,4-d]tetrahydropyrimidines 7 and 9 with different substituted patterns have been developed, which provide rapid access to a library of compounds 7 and 9 in medium to excellent yields, by using N-methyl-α-aryl(alkyl)aminomaleimides, amines, and aldehydes as reactants. The catalyst and the ratio of reactants were
已开发出新型脯氨酸催化的多组分反应(MCR),用于合成具有不同取代模式的稠合吡咯并[3,4- d ]四氢嘧啶7和9,可在中等至极好的条件下快速访问化合物7和9的文库。通过使用N-甲基-α-芳基(烷基)氨基马来酰亚胺,胺和醛作为反应物,可得到苯甲酸酯。发现催化剂和反应物的比例对这些反应有显着影响,并提出了合理的机理。
