[reaction: see text] An approach to the densely functionalized fluorocyclopropane 14, a key framework toward the synthesis of mGluR 2 receptor agonist MGS0028 (1) is reported. The Trost AAA reaction enantioselectively introduced the key allylic stereogeniccenter and the alpha-fluoroester moiety. Stereoselective epoxidation followed by intramolecular epoxide ring opening efficiently constructed the 1-
