Graphical Abstract:
 Described synthesis of 5-bromo substituted oxindoles linkages in spirocyclic butenolides exhibit relatively dependence of the structure-reactivity relationships of N-substituted isatines, dimethyl acetylenedicarboxylate and triphenylphoshine. The study of the stereochemistry of the atom C(2) of the spiro compounds was also unambiguously confirmed by single crystal X-ray analysis.
