Coming full circle: CuI/L‐proline‐catalyzed coupling of substituted 3‐iodoprop‐2‐en‐1‐ols and terminal alkynes followed by copper‐mediated cycloisomerization produced furans in good yields. This method allows the assembly of 2,3,4‐ and 2,3,5‐trisubstituted furans, as well as 2,3,4,5‐tetrasubstituted furans.
