Novel group II metabotropic glutamate receptor (mGluR) antagonists, 3-alkoxy-2-amino-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid derivatives 11 and 12, were discovered by the incorporation of a hydroxy or alkoxyl group onto the C-3 portion of selective and potent group II mGluR agonist 5, (1R,2S,5R,6R)-2-amino-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid. Among these compounds, (1R,2R
