• , affording the corresponding Au(I) complexes in moderate to high yields. Keywords: axially chiral ligand; gold; N-heterocyclic carbenes; N-naphthyl framework; Introduction During the past decade, with an explosive growth of asymmetric homogeneous gold catalysis in C–C, C–O, or C–N bond formations, the

• type of axially chiral ligand 7 with an N-naphthyl framework (Figure 2) instead of traditional binaphthyl framework [15]. Their palladium complexes 8 showed high stereoselectivities in asymmetric allylic arylations to achieve the kinetic resolution of Morita–Baylis–Hillman adducts, affording up to 99
