A multicomponent tether catalysis protocol for the synthesis of 4-(pyridin-2-ylmethyl)-2-aminopyrroles (PMAPs) was constructed by simply refluxing a mixture of ethyl 2-(pyridin-2-yl)acetates 1 and various types of arylglyoxal monohydrates 2 and different heterocyclic ketene aminals 3 in EtOH solvent. Based on this reaction, a series of highly functionalized PMAPs were obtained through a novel cascade reaction accompanied by a decarboxylation mechanism. As a result, the pyridin-2-ylmethyl was successfully introduced in the target compounds, and a library of PMAPs were easily constructed using the cascade reaction described in this study. This protocol demonstrated that the most important feature was the decarboxylation reaction of the 2-(pyridin-2-yl)acetates 1, which can be used in the synthesis of pyridin-2-ylmethyl-substituted heterocycles, including pyrroles, pyridines, quinolones, and other heterocyclic compounds resembling those found in nature.
