Application

(S)-SIPHOS-PE is a chiral spiro phosphoramidate ligand that can be used to synthesize:
  • Spiroindolenines by Pd-catalyzed intramolecular dearomative arylation of haloaryl-3-substituted indoles.
  • Enantioselective conjugate addition compound by Cu-catalyzed 1,4-addition of diethylzinc (Et2Zn) to cyclic enones.
  • Octaketide natural products via rhodium-phosphoramidite catalyzed alkene hydroacylation.
