A metal‐free, phosphine‐catalyzed intramolecular “umpolung Michael addition” on alkynes to form spiroindol(en)ines is reported. This nucleophilic catalysis enables the formation of a wide scope of five‐ and six‐membered spiroindol(en)ines in moderate to excellent yields in batch as well as under continuous‐flow conditions. Triphenylphosphine‐catalyzed nucleophilic activation of alkynes allows the exclusive
