A novel, facile, and efficient Lewis-acid-catalyzed [4 + 1] annulation protocol for the construction of functionalized polycyclic-fused furans is developed. This methodology is free of transition metals and ligands and provides a rapid synthetic route to divergently orientated polycyclic furans in good yields. In addition, this protocol can also be used to synthesize multisubstituted furans.

The rhodium(II)-catalyzed reactions of iodonium ylides with electron-deficient and conjugated alkynes have been examined. These reactions provide a rapid route to the preparation of furan derivatives with a variety of substituents on the furan ring.
