azepane into their corresponding 3-exo-alkenyl lactams via the transient formation of 3-alkoxyamino lactams followed by a Wittig-like C(sp3)–O bond olefination with stabilized ylides from phosphonium salts mediated by t-BuOK. Additionally, as a proof of the synthetic effectiveness of this novel methodology, the first synthesis of the natural product callylactam A was achieved through a TiCl4-catalyzed
