A palladium-catalyzed asymmetric (4 + 3) cycloaddition was developed for the enantioselective synthesis of trifluoromethylated spirooxindoles. The reaction proceeded smoothly in a one-pot manner without the need for a Bronsted base, providing a cost-effective and efficient strategy for the construction of optically pure medium-sized rings.
A palladium-catalyzed asymmetric (4 + 3) cycloaddition of N-2,2,2-trifluoroethylisatin ketimines with 2-methylidenetrimethylene carbonate was reported to enantioselectively afford trifluoromethylated spirooxindoles in moderate yields and good to excellent ee values. Experimentally, the reaction proceeded smoothly in the absence of a Bronsted base in a one-pot manner, which paved a way for efficient and cost-effective construction of optically pure trifluoromethylated medium-sized rings.
