Abstract
A novel imidazolium-based binol receptor 4 has been synthesized and used as a chirality conversion reagent for general amino acids with higher d-form selectivity compared to other guanidinium-based receptors. Favorable solubility in chloroform enabled 4 as an effective chiral extractant for the resolution of racemic amino acids.
