Abstract
Two chiral ammonium ionic liquids 1a and 1b have been newly synthesized from commercially available (+)-cis-2-benzamidocyclohexanecarboxylic acid. These CILs have been demonstrated to be efficient organocatalysts for asymmetric Michael addition of aldehydes to nitroolefins with excellent yields (up to 99%), high enantioselectivities (up to 90%) and modest to high diastereoselectivities (syn/anti ratio up to 99/1).
