They could also obtain the BHMF in a high isolated yield of 95% by using a high equivalent amount of manganese dioxide (2 equiv. MnO2) at room temperature in THF. Later, Zang and co-workers designed and synthesized molybdenum-and tungsten-based catalysts [CTAB]4Mo8O26 and used for the oxidation of DHMF to BHMF under air in solvent acetic acid. 94% yield of BHMF could be achieved under optimal conditions (mass ratio of furoin/DHMF to catalyst = 10/1, 10 mL acetic acid, 110 °C, 2 h). Notably, to the best of our knowledge, highly selective and efficient aerobic oxidation of DHMF to BHMF in neat water at atmospheric pressure of air and low temperature using a catalytic amount of base catalyst K2CO3 has not been reported to date.
