An unprecedented Michael/intramolecular etherification cascade reaction of phenyl vinyl
selenone with 3‐hydroxyoxindoles under aqueous basic conditions at room temperature is
described. The method provides a domino access to new spirooxindole 2, 2‐disubstituted
oxetanes in moderate to good yields under mild reaction conditions.
