Synthetic Route of 50777-76-9, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.50777-76-9, Name is 2-(Diphenylphosphino)benzaldehyde, molecular formula is C19H15OP. In a patent, introducing its new discovery.
An efficient and highly enantioselective (up to 95% ee) Cu-catalyzed method for asymmetric conjugate addition (ACA) of alkylzinc reagents to acyclic disubstituted nitroalkenes is presented. Reactions are typically effected at ambient temperature in the presence of 2 mol % chiral dipeptide phosphine and 1 mol % (CuOTf)2·C6H6. Nitroalkenes bearing aromatic as well as aliphatic substituents readily undergo asymmetric additions.
