As a part of our study of the cancer-specific protease PSMA (prostate-specific membrane antigen) we present a stereoselective synthesis of conformationally constrained glutamate mimetics. Key intermediates are azabicycloalkenes which are synthesized via diastereoselective or enantioselective imino-Diels–Alder protocols. The versatility of the route is demonstrated with the preparation of Asp, Glu and
