Abstract

Indazoloquinazolines are a class of heterocyclic compounds consisting of fused indazole and quinazoline fragments that can be connected with nitrogen atom as a fusion point. The tetracyclic scaffolds built that way include indazolo[2,3-c]quinazolines, indazolo[2,3-a]quinazolines, and indazolo[3,2-b]quinazolines. The natural occurrence of this compound class is rare, however, the indazolo-fused quinazolines possess a wide range of biological activities. Among those, indazolo[2,3-a]quinazolines have shown high antibacterial activity. The synthetic routes towards indazoloquinazolines can be categorised into several groups: 1) metal-catalyzed and metal-free intramolecular cyclizations; 2) metal-catalyzed and metal-free intermolecular reactions; 3) reductive intramolecular cyclization; 4) multicomponent assembly reactions.
