An electrochemical strategy to the assembly of tricyclic spiro dihydrofuran scaffold via the reaction of aryl aldehyde and dimedone has been developed successfully. This protocol has the advantages of high yields, wide application scope and an environmental benign procedure compared with the reported methods.

5-dimethylcyclohexane-1,3-dione and 1,3-indandione to selectively afford spirodihydrofuran and cyclopropane derivatives, promoted by molecular iodine and dimethylaminopyridine under mechanical milling conditions, has been demonstrated. The products were obtained in good to excellent yields. A possible mechanism of this unusual reaction process is proposed.

A new iodonium ylide‐based three‐component reaction for the synthesis of highly functionalized 2‐spirosubstituted dihydrofurans starting from readily available common reactants has been developed undermicrowaveirradiation. The procedure is facile, avoiding time‐consuming and costly syntheses, tedious work‐up and purifications of precursors as well as protection/deprotection of functional groups.
