Spirocyclopenteneoxindole derivatives were obtained by stereoselective triphenylphosphine-catalyzed [3+2] cycloadditions of ynones and alkylidene oxindole derivatives. This approach is based on the Michael addition of ynones to alkylidene oxindole derivatives, followed by intermolecular [Formula: see text]-addition using 50 mol% triphenylphosphine as catalyst.
