Abstract
C1 -Symmetric chiral ammonium salt catalysts induced a kinetic resolution of racemic α-nitrolactones through an asymmetric ester-amide exchange reaction. The corresponding amides were obtained with high enantioselectivities and high S (= k fast / k slow) values. This reaction system is a useful approach for obtaining carbocyclic quaternary α-nitroamides as chiral building blocks.
