From C2- to D2-symmetry: atropos phosphoramidites with a D2-symmetric backbone as highly efficient ligands in Cu-catalyzed conjugate additions
Atropos phosphoramidites with the D2-symmetric biphenyl backbone were diastereoselectively prepared with ease from achiral tetrahydroxy biphenyls. This type of ligands is proved to be highly efficient in the Cu-catalyzed conjugate additions of diethylzinc to alpha,beta-unsaturated ketones and nitroalkenes. The unique D2-symmetric backbone endows the ligands with an excellent chiral environment.
However, they have proven to be challenging because of the mutual inactivation of both catalysts. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 538-58-9
