Reaction of 5,5-dimethylcyclohexane-1,3-dione (dimedone), aldehydes and cyanogen bromide in the presence of triethylamine leads to the selective formation of spiro dihydrofurans in moderate to good yields at room temperature.

The use of supported Cu complex on mesoporous as a novel, efficient, heterogeneous, reusable and green catalyst for the synthesis of spiro-dihydrofuran derivatives is reported. This methodology is effective for the reaction of dimedone with a wide range of aldehyde in the presence of BrCN and triethylamine. The structure of catalyst was characterized by different techniques such as EDX, SEM, TGA, ICP-OES, XRD, TEM, FT-IR, and BET. The recycled nanocatalyst was used at least five times with no significant loss of its activity.
