Chiral ionic liquids (CILs) have potential application in asymmetric organic synthesis, chiral drug synthesis,
stationary phases in chiral chromatography, optical resolution of racemic mixtures and chiral shifting reagents
in NMR spectroscopy. CILs may possess central, planar or axial chirality and can be synthesized from
chiral pool or via asymmetric synthesis. Although, the synthesis of these species is difficult and costly yet in view
of their prominent properties and wide range of applications, recently large number of CILs have been synthesized
and employed in synthetic strategies. The present review enlightens various protocols for the synthesis of
CILs. The use of these chiral ionic liquids as organocatalysts in synthetically important asymmetric reactions has
also been discussed.
Keywords: Ionic liquids, chirality, organocatalysts, asymmetric synthesis, enantioselectivity.
