Coordination‐Mediated Optical Resolution of Carboxylic Acids with <i>O, O</i>′‐Dibenzoyltartaric Acid

Abstract

Chiral recognition in the coordination sphere of a calcium ion that is coordinated to a simple tartaric acid derivative offers new possibilities for the preparative-scale resolution of nonbasic compounds. An example of a mixed calcium salt formed upon resolution of racemic carboxylic acids is shown on the right.
