A palladium-catalyzed intramolecular amidation of arylcarbamic acid derivatives bearing 1,3-diene moiety with or without external nucleophiles is described. The tandem cycloamidation and nucleophilic allylic substitution are successfully applied to the construction of the spiro[indoline-3,3'-pyrrolidine] skeleton as well as contiguous stereogenic centers with an aim of synthesizing spirocyclic oxindole alkaloids.
