intermolecular alkynylation reactions of various alkoxy, acetoxylactams, and hydroxylactams. This chemistry broadens the scope of iron catalysis by highlighting new aspects of iron salts σ-Lewis acidity. More importantly, this approach is amenable to an unprecedented tandem intermolecular alkynylation/intramolecular hydration sequence affording expedient access to a new carbonyl structures.
