Author's Final Manuscript
The first report of Lewis acid use in intramolecular Rauhut-Currier reactions is described. Titanium Lewis acids lead to rapid Rauhut-Currier reactions in the case of two classic substrates. More importantly, titanium and tin Lewis acids were the only successful reagent for a more complex substrate, thereby illustrating the potential for Lewis acid reagents to facilitate challenging intramolecular Rauhut-Currier reactions that fail with traditional reagents.
