The Impact of Solvent and the Receptor Structure on Chiral Recognition Using Model Acyclic Bisamides Decorated with Glucosamine Pendant Arms

[Image: see text] We investigated the influence of various factors (including solvent mixtures) on chiral recognition of chiral carboxylates, using the titration method under (1)H NMR control. We found that strong binding carboxylates (geometrical matching) is not enough for the satisfactory differentiation of enantiomers. Moreover, solvent mixture studies indicate a significant influence of environment on the formation of diastereomeric complexes and variations among them. Our findings offer insights into the complementarity of chiral recognition processes.
