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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
