(-)-(Z)-2,3-Methano-L-glutamic acid, a potential mGluR agonist, has been synthesized for the first time in 40% overall yield from a homochiral amino pentenoate as an easily available precursor. A conveniently protected (-)-(Z)-cyclo-aspartic acid derivative was the key intermediate, homologation of the carboxylic acid having been accomplished via the Arndt-Eistert procedure.
