*Antimony potassium tartrate, an anion, that forms diastereomeric salts with chiral cations.
*Camphorsulfonic acid, an acid that forms diastereomeric salts with chiral amines
*1-Phenylethylamine, a base that forms diastereomeric salts with chiral acids. Many related chiral amines have been demonstrated.
The chiral pool consists of many widely available resolving agents.
