Abstract

In this research, an efficient one-pot synthesis of pyrimido[4,5-d]pyrimidine derivatives has been described using a new DABCO-based ionic liquid catalyst formulated as [C4(DABCO-SO3H)2]. 4ClO4. Some of the important features of the reported method are short reaction times, easy work-up and isolation of the products from the reaction media, high yields and reusability of the catalyst. Keywords: DABCO; Heterocyclic compound; Ionic liquid; Pyrimido[4,5-d]pyrimidines; [C4(DABCO-SO3H)2].4ClO4
