Significance
The authors report the creative synthesis of optically active [AB]-type oligomers (R)-2, (S)-4, and (S)-6. This is done via TCNE and TTF additions to alkyne-substituted 1,1′-binaphthalene derivatives shown above. Their ¹H and ¹³C NMR spectra reveal complex conformational equilibria in solution for the oligomers.
