The direct enantioselective amination of nitroolefins has been performed with l-tert-leucine-derived squaramide-scaffold bifunctional phase-transfer catalysts under base-free and water-rich conditions with low catalyst loading (0.5-1 mol%) to provide 2-am

It′s just a phase: Environmentally benign title reaction was achieved under neutral phase-transfer conditions in the presence of 0.05 mol% of a chiral bifunctional ammonium bromide. The importance of bifunctional design of the chiral phase-transfer catalysts (PTC) was clearly shown in the transition-state model of the reaction based on the single-crystal X-ray structure. Bn=benzyl, Boc=tert-butoxycarbonyl.
