  A three-component condensation reaction between 2-aminopyridine, an aldehyde and an isonitrile catalyzed by scandium triflate affords derivatives of 3-aminoimidazo[1,2-a]pyridine; aminopyrazine reacts similarly. A library of heterocycles, prepared in high yield by parallel synthesis and purification on an ion-exchange resin, was subjected to further reactions at the amino group.

  Over the last twenty years. the Groebke-Blackburn-Bienayme (GBB) reaction has been emerged as a powerful tool to access different nitrogen-based heterocycles as privileged scaffolds in medicinal chemistry. This multicomponent reaction is usually catalyzed by ordinary Bronsted or Lewis acid catalysts. Herein, we present a comparative study on the catalytic efficiencies of different rare earth triflates in GBB reactions under microwave heating, involving 2-aminopyridine or 2-aminothiazole, as aminoazole component, and different aldehydes and aliphatic isocyanides. The use of gadolinium(III) triflate as cheaper alternative catalyst for the most commonly used scandium(III) titillate was acknowledged for the first time, and a library of twenty three imidazo[1,2-a]pyridines and imidazo[2,1-b]thiazoles could be obtained in good to excellent yields.
