In the presence of a catalytic amount of Pd(TFA)2 and a chiral Pyox ligand, an oxidative Heck reaction between arylboronic acids and 4-substituted or 4,4-disubstituted cyclopent-1-enes provides arylated products with concurrent creation of two stereocenters in good yields with excellent diastereo- and enantioselectivities under an atmosphere of oxygen.
