A concise method is reported for the synthesis of 2-aminobicyclo[3.2.0]heptane-2,7-dicarboxylic acid, a close analogue of the glutamate receptor ligand LY354740, in both enantiomeric forms. The strategy features the creation of the core structure at the start of the synthesis via a photochemical [2 + 2] cycloaddition reaction, an efficient resolution procedure using a chiral oxazolidinone, and requires
