Highly functionalized cyclopropanes can be produced with excellent enantioselectivity through an a mine-catalyzed organocatalytic cyclopropanation process (see scheme). Catalytically generated asymmetric ammonium ylides mediate the reaction, and the cyclopropane products can be produced as either enantiomer by using quinine- or quinidine-derived catalysts.
