Synthesis of optically active oligomers consisting of chiral phosphorus atoms: capture of an intermediate between a polymer and a small molecule

In this study, we captured an intermediate between a polymer and a small molecule. The optically active oligophosphine (S,R,S,S,R,S)-3 was synthesized, and behaviors of (S,R,S,S,R,S)-3 and other optically active oligophosphines were investigated in detail.
