An asymmetric Dieckmann condensation towards spirocyclic oxindoles and aza-oxindoles catalyzed by amino acid-derived phosphonium salt has been developed, which expanded the applicability of asymmetric phosphonium salt catalysis in the production of 1,3-dicarbonyl compounds. This reaction is distinguished by its mild conditions (?20 °C), low catalyst loading (3–5 mol%), and broad substrate scope (25 examples). Control experiments revealed that both the catalyst‘s phosphonium skeleton and H-bonding site were required. Product transformations and a gram scale experiment were also carried out. (Figure presented.).
