Applicazioni

(S)-P-Phos can be used as a ligand:
  • In the asymmetic hydrogenation reactions.
  • For the preparation of chiral ketone functionalized polymers by copolymerization reaction.
  • To synthesize chiral alkynes by asymmetric hydroalkynylation of nonpolar alkenes or norbornadienes using iridium catalyst.
  • In the selective allylic alkylation of indoles using palladium catalyst.

Ligand employed in the asymmetic hydrogenation of ß-keto esters, 2-arylacrylates, aryl ketones , and other substrates.

This Account outlines our efforts in the design and synthesis of a family of highly effective atropisomeric dipyridylphosphine ligands (P-Phos and its variants) and in the development of their widespread applications in transition-metal-catalyzed asymmetric reactions including hydrogenation, hydrosilylation, and C-C

Following our previously reported pyridinyl phosphine oxides as antitumor agents, we targeted the commercially available C(2)-axial chiral organophosphine ligand catalysts, such as 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (BINAP) 1 and 2,2',6,6'-tetramethoxy-4,4'-bis(diphenylphosphino)-3,3'-bipyridine (P-Phos) 2 as a convenient source for producing organophosphine oxides as antitumor leads.
