title: DABCO-catalyzed [3 + 2] annulation of sulfamate-derived cyclic imines with isocyanoacetates: synthesis of sulfamate-fused 2-imidazoline.
abstract: DABCO-catalyzed [3 + 2] annulation reaction of sulfamate-derived cyclic imines with isocyanoacetate proceeds under mild conditions, providing sulfamate-fused 2-imidazolines in moderate to excellent yields with moderate to excellent diastereoselectivities.
