Résumé

A three-component condensation reaction between aminopyrazolo[3,4-d] pyrimidine, an aldehyde, and an isocyanide catalyzed by scandium triflate yields a series of heterocyclic derivatives of imidazo[1,2-c]pyrazolo[3,4-d]pyrimidine in good yields, exhibiting interesting fluorescent properties.
