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.

The term MIRC reaction is defined. Examples of the construction of three, five, six and sevenmemberedrings using alkylthiolates and LDA as nucleophiles are presented.

To reach densely functionalized 1-azabicyclo[3.3.1]nonane frameworks synthesis, a stereocontrolled bridging Michael addition involving an unexplored C-5/C-6 disconnection strategy was studied. 1-Azabicyclo[3.3.1]nonane scaffolds have been diastereoselectively elaborated in fairly good yields by two concise pathways implying pyrrolidine derivative organocatalyst or enantiopure 1-phenylethylamine.
