Presently, very few strategies are available for directly converting glucose‐like compounds to 5‐ethoxymethylfurfural (EMF), a remarkable biofuel candidate. We report here on this conversion effectively using aluminum‐based mixed‐acid catalyst in co‐solvent medium. The combination of aluminum triflate and Amberlyst‐15 exhibited an admirable synergistic catalytic effect for the one‐pot cascade conversion of glucose. Importantly, the interfusion of dimethyl sulfoxide into ethanol as co‐solvent medium can significantly promote the formation of EMF reducing the extent of side reactions. Based on this protocol, the effects of key process variables on the conversion of glucose were investigated via response surface methodology, leading to EMF in up to a 48.1% yield. The catalytic system can be separated with the reaction products and demonstrates reusability. Also, the generality of developed catalytic strategy can extended to synthesize EMF directly from glucose‐based polysaccharides, such as sucrose and starch.
