enantioselective Mannich-type reaction promoted by chiral binaphthyl-modified bifunctionalorganocatalysts is described. The treatment of α-fluoro-β-ketoesters with N-Boc imines under mild reactionconditions afforded the corresponding β-aminated α-fluoro-β-ketoesters with excellent enantioselectivities (upto 98% ee).Key Words : Mannichreaction, Asymmetric catalysis, Bifunctional organocatalyst, α-Fluoro-β-ketoesters
