## Abstract The formal 1,3‐cycloaddition of 2‐diazocyclohexane‐1,3‐diones **1a**–1**d** to acyclic and cyclic enol ethers in the presence of Rh^II^‐catalysts to afford dihydrofurans has been investigated. Reaction with a __cis/trans__ mixture of 1‐ethoxyprop‐1‐ene (**13a**) yielded the dihydrofuran
