An efficient method for preparing conformationally restricted cyclopentenyl-glutamate analogues in a regioselective and diastereoselective manner has been developed using a formal [3 + 2] cycloaddition reaction of dehydroamino acids. Methods for preparing optically active versions of these compounds have also been devised. Of these compounds, (S)-2 is an agonist at the mGlu5 (EC50 18 muM) and mGlu2 (EC50 45 muM) receptors.

The novel, optically active and conformationally restricted L-glutamate analogues 6, 7 and 11 have been prepared via the PPh3 catalysed cycloaddition of the allenes 2 and 9 with the chiral oxazolidinone 1.
