A novel palladium-catalyzed regio- and stereoselective dienylation via a combination of cascade carbopalladation and subsequent desulfitative coupling after the base-induced ring opening of sulfolenes has been described. In this reaction, a range of Z-selective conjugated dienes bearing oxindoles or isoquinolinediones are obtained in moderate yields.
