Chiral Phosphoric Acid Promoted Chiral 1H NMR Analysis of Atropisomeric Quinolines
An efficient enantioselective NMR analysis of atropisomeric quinolines in the promotion of chiral phosphoric acid is described, in which a variety of racemic 4-aryl quinolines were well-recognized with up to 0.17 ppm ΔΔδ value. Additionally, the optical purities of different nonracemic substrates co...
