The three‐component condensation of 3‐amino‐5‐alkylthio‐1,2,4‐triazoles with aromatic aldehydes and β‐ketoester was studied to develop a regioselective Biginelli‐like reaction. The results indicated that the reaction solvent and the properties of the β‐ketoester component displayed great influence on the regioselectivity. This is the first report about the regioselectivity of the aminotriazole‐based Biginelli‐like r...
