Abstract Fused heterocyclic systems with 1,2,4‐triazole scaffold arouse great interest from researchers in the branch of heterocyclic and medical chemistry because of their wide biological activities as they are considered as fungicidal, antimicrobial, analgesic, bronchodilators, antioxidant, anti‐inflammatory agents, and they are G‐quadruple stabilizers; the molecular docking data for coumarin‐containing 1,2,4‐triazoles indicate their ability to act as a urease inhibitor. Therefore, the present review aims to investigate new trends in the chemistry of heterocycles incorporating thiazolo[3,2‐b][1,2,4]triazoles, thiazolo[2,3‐c][1,2,4]triazoles, thiazino[5,1‐b][1,2,4]triazoles, thiazino[3,4‐b][1,2,4]triazoles, triazolothiazepines, and their biological characteristics. The main sections discuss: (a) the synthetic routes to the production of substituted fused heterocyclic systems, which include condensation reactions, multiple bond annulation, and the reactions of electrophilic heterocyclization. (b) Description of chemical and biological characteristics of these fused heterocycles.
