Abstract: A new efficient synthesis of racemic (R*,R*)-Pyrphos ligand based on aza-Michael addition reaction of 2,3-bis(diphenylphosphoryl)buta-1,3-diene with ammonia followed by the reduction of resulting 3,4-bis(diphenylphosphoryl)pyrrolidine is proposed. The starting reactants are available but-2-yne-1,4-diol and chloro(diphenyl)phosphine.

Keywords: Pyrphos, aza-Michael addition, intramolecular cyclization, reduction, phosphines, X-ray analysis.
