Chirality induction on achiral N-methyl aromatic amide oligomers bearing terminal carboxy groups with chiral amines.
Novel unsymmetrical N-methyl aromatic amide oligomers bearing two carboxy groups at both ends were synthesized and their complexation with various optically active amines in solution was investigated using circular dichroism (CD) spectroscopy. The complexes showed a characteristic induced CD in the absorption region due to the aromatic amide reflecting the absolute configuration of the chiral amines.
