Au‐ff on a trip: Chiral ligands (L*) and chiral anions [(S)‐TriPAg] are employed in the gold(I)‐catalyzed enantioselective intramolecular additions of hydrazines and hydroxylamines to allenes. These complementary methods allow access to chiral vinyl isoxazolidines, oxazines, and differentially protected pyrazolidines. PNB=para‐nitrobenzoyl.
