  Enantioselective Synthesis of Imidazolines with Quaternary Stereocenters by Organocatalytic Reaction of N-(Heteroarenesulfonyl)imines with Isocyanoacetates

  摘要：

  An organocatalytic enantioselective Mannich-type reaction of isocyanoacetate with N-sulfonylimines catalyzed by chiral thioureas derived from quinine yielded 2-imidazolines with high diastereo- and enantioselectivities (up to >99:1 dr. and 96% ee). This reaction provided a convenient route to access various imidazolines and related alpha,beta-diamino acids having a quaternary carbon center in high enantiomeric purities.
