Abstract
A new, concise and efficient method of one-pot synthesis of 3-(furan-2-yl)-4H-chromen-4-ones was developed using K10 montmorillonite catalysis under solvent-free conditions. The procedure of the synthesis of 3-(furan-2-yl)-4H-chromen-4-ones was that 1-(2-hydroxyphenyl)butane-1,3-diones and 2,5-dimethoxy-2,5-dihydrofuran underwent a process of α-alkoxyalkylation in the presence of K10 montmorillonite at 80 °C for 0.5 h and continuously at 120 °C for another 0.5 h. The advantages of this method were that it was solvent-free, the K10 montmorillonite was recyclable and it had an easy work-up.
