(Chemical Equation Presented) (R)-Proline catalyzes the amination reaction of functionalized indane carboxaldehydes and allows for the efficient enantioselective synthesis (>99% ee) of the metabotropic glutamate receptor ligands (S)-AIDA and (S)-APICA.

Heating a mixture of α-aryl ketone with (R)-phenylglycinol produces a mixture of imine and 1,3-dioxazolidine. Treatment of this mixture with trimethylsilyl cyanide followed by transformation of nitrile to ester gives Strecker-type reaction products. The diastereoselectivity of the generated α-amino esters is from 2/1 to 7/1, and the (R,S)isomer is found as the major product. The (R,S) and (R,R)isomers can be separated by conversion to their N-Cbz or cyclization derivatives. Using this methodology, four antagonists of metabotropic glutamate receptors, (S)-αM4CPG, (S)-MPPG, (S)AIDA, and (S)- APICA, are synthesized.

The synthesis of two rigidified phenylglycine analogues is disclosed. The cyclic analogue 1 of (R,S)-α-methyl-4-phosphonophenylglycine (MPPG) is shown to be a particularly interesting pharmacological tool, for it is a group II selective mGluR antagonist that possesses an inverse agonist-like action.
