Palladium-catalyzed three-component [3 + 2] cycloaddition of propargyl trifluoroacetates, ethylidene malononitriles, and allyltributylstannane.
A novel Pd(0)-catalyzed three-component [3 + 2] cycloaddition of propargyl trifluoroacetates 1, ethylidene malononitriles 2, and allyltributylstannane 3 afforded a variety of multisubstituted cyclopentenes 4 in good to high yields under mild reaction conditions.
