oxindoles that affords access to both the linear and reverse‐prenylated products. Both 3‐alkyl‐ and 3‐aryloxindoles performed well under our optimized reaction conditions. The regiodivergent alkylation of monoterpene‐derived electrophiles using this methodology was also investigated. The utility of this methodology in naturalproduct synthesis was demonstrated through the efficient total syntheses of four
