A totally new acid-free domino process to access highly functionalized bicyclic gamma-and delta-lactams starting from commercially available and inexpensive ethoxymethylene derivatives is reported. Mechanisms elucidated by computational calculations led to new reaction conditions that boosted the yields up to 3.5 times higher.
