The addition of lithiatedalkoxyallenes to N‐tosylimines followed by base‐, silver‐, or gold‐promoted cyclization of the addition products efficiently provides 2,5‐dihydropyrroles, which are excellent substrates for further transformations. Acids promote the hydrolysis of the enol ether moiety to deliver pyrrolidin‐3‐ones, and bases promote the aromatization to the elusive 3‐alkoxypyrroles.
