Development of Binaphthyl-Based Chiral Dienes for Rhodium(I)-Catalyzed Asymmetric Arylation of N,N-Dimethylsulfamoyl-Protected Aldimines

A variety of binaphthyl-based chiral dienes were synthesized and utilized as steering ligands for the enantioselective arylation of N,N-dimethylsulfamoyl-protected aldimines with arylboronic acids, and moderate to good yields and up to 84% ee were achieved.
