Addition of monomer A to CuI gave racemic helical metallopolymer 1.
Introducing an enantiomerically pure initiating group, (R)-C or (S)-C, lent stereoselectivity to the polymerization reaction, yielding M-1 or P-1 preferentially.
Formation of helical polymers from enantiomerically pure monomer (S)-B also biased the reaction toward the formation of enantioenriched P-2.
