A highly efficient asymmetric arylation of cyclic N-sulfonyl aldimines with arylboronic acids catalyzed by a rhodium/ sulfur-olefin ligand complex under mild conditions is described. A wide range 4-aryl-3,4-dihydro-1,2,3- benzoxathiazine 2,2-dioxides were obtained in extremely high yields (93-99%) and high enantiomeric purities (97-99% ee).

A Ni(ii)-catalyzed asymmetric addition of arylboronic acids to cyclic aldimines and ketimines is reported. Our tropos phosphine-oxazoline biphenyl ligand is crucial for the high catalytic activity, which coordinates to Ni(ii) to form a complex with a single axial configuration. The desired chiral amine products could be prepared with excellent yields (up to 99%) and enantioselectivities (up to 99.8%) under mild reaction conditions.

New, simple, sulfinamide-based branched olefin ligands have been developed and successfully used in Rh-catalyzed asymmetric arylations of cyclic ketimines, providing efficient and highly enantioselective access to valuable benzosultams and benzosulfamidat
