ester enolates are highly efficient nucleophiles for the synthesis of conformationally constrainedglutamatesvia domino sequences of Michael additions and subsequent ring closures (MIRC). This protocol allows the generation of 3–6-membered ring systems in high yields and excellent diastereoselectivities. Depending on the reaction conditions either carbocyclic or heterocyclic ring systems are obtained.
