A variety of N-substituted pyrroles have been synthesized by reacting γ-diketones with amines, diamines or triamine in the presence of silica sulfuric acid (SSA) at room temperature under solvent-free conditions. The experiment protocol features simple operations, and the products are isolated in high to excellent yields (70–98%).
通过在室温下在无溶剂
硫酸二氧化硅(S
SA)存在下,使γ-二酮与胺,二胺或三胺反应,可以合成出多种N-取代的
吡咯。该实验方案操作简单,并且分离出的产品产率高至优异(70-98%)。
