Scalable Synthesis of (+)-2-Amino-3-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic Acid as a Potent and Selective Group II Metabotropic Glutamate Receptor Agonist

Abstract

We successfully synthesized the potent and selective group II mGluR agonist (+)-1 (MGS0008) via a process incorporating the key step of efficient fluorination of epoxide (±)-5c. This method would be adaptable to large-scale synthesis to produce (+)-1 in multi-gram quantities.
