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.

Packaging:

50, 250 mg in amber glass bottle
