In the 3-component-reaction comprising the interaction of an H-active compound with s-triazine (2) and a secondary amine (5), cyanamide (1) may represent the NH-active reactant. Initiated by the nucleophilic attack of 2 by 1, the reaction proceeds via the intermediary steps 3 and 4 and forms, under the action of 5, the dehydro-N-Mannich-bases 6 as the final products. The reaction mechanism postulated
在包括H-活性化合物与s-三嗪(2)和仲胺(5)的相互作用的3-组分反应中,
氰胺(1)可以代表NH-活性反应物。通过的亲核攻击发起2由1,该反应经由中间步骤前进3和4和形式,的作用下5中,脱氢N-曼尼希碱基6作为最终产品。假定的反应机理由中间体4的可实现分离及其随后通过5转化为6的支持。
