Applications of earth abundant transitions metals such as iron have become increasingly appealing to synthetic chemistry because of their high abundance and low cost. We herein report the use of an environmentally begign transition metal as a Lewis acid to catalyze an intramolecular carbonyl olefin metathesis with sequential carbocation trapping to produce various 6, 5 and 6, 6 fused ring systems. The reaction is compatable with aromatic and aliphatic substrates. The resultant multi-ring systems have applications as precursors to natural products such as Carexane.
