A short diastereoselective synthesis of cis-(2S,4S) and cis-(2R,4R)-4-hydroxyprolines

A concise synthesis of (2R,4R)-4-hydroxyproline (1) and (2S,4S)-4-hydroxyproline (2) has been developed in enantiomerically pure form from commercially available starting materials with excellent diastereoselectivity. The tightly bound chelation controlled transition state formed during the 5-exo-tet ring closure reaction is assumed to be the origin of high diastereoselectivity.

Design and synthesis of APTCs (aminopyrrolidinetricarboxylic acids): Identification of a new group III metabotropic glutamate receptor selective agonist

A new family of mGlu receptor orthosteric ligands called APTCs was designed and synthesized using a parallel chemistry approach. Amongst 65 molecules tested on mGlu4, mGlu6 and mGlu8 subtypes, (2S,4S)-4-amino-1-[(E)-3-carboxyacryloyl]pyrrolidine-2,4-dicar

Ex-chiral pool synthesis and receptor binding studies of 4-substituted prolinol derivatives

Starting from natural 4-hydroxyproline, preparation of the four possible stereoisomers of 4-amino- and 4-aminomethyl-substituted prolinol derivatives, respectively, was accomplished by chemo- and regioselective functional group transformations at the 2- and 4-positions of the pyrrolidine moiety. These building blocks were used as valuable precursors for the preparation of new methoxybenzamide derivatives. Dopamine and serotonin binding studies involving the subtypes D1, D2long, D2short, D3 and D4 as well as 5-HT1A and 5-HT2, respectively, displayed interesting structure activity relationships, especially with respect to the absolute and relative configuration of the test compounds. As a complement to the D3 receptor preferring aminomethylpyrrolidine FAUC 21, the (2R,4R)-aminoprolinol derivative ent-24 (FAUC 65) preferentially recognizing the D4 subtype was developed.

Synthesis of the four isomers of 4-aminopyrrolidine-2,4-dicarboxylate: Identification of a potent, highly selective, and systemically-active agonist for metabotropic glutamate receptors negatively coupled to adenylate cyclase

The four isomers of 4-aminopyrrolidine-2,4-dicarboxylate (APDC) were prepared and evaluated for their effects at glutamate receptors in vitro. (2R,4R)-APDC (2a), an aza analog of the nonselective mGluR agonist (1S,3R)- 1-aminocyclopentane-1,3-dicarboxylat

Asymmetric syntheses of all four isomers of 4-amino-4-carboxyproline: Novel conformationally restricted glutamic acid analogues

Asymmetric syntheses of all four isomers of 4-amino-4-carboxyprolines, i.e. (2S,4S)-3, (2S,4R)-4, and their corresponding enantiomers, as novel conformationally restricted analogues of glutamic acid, were performed from trans-4-hydroxy-L-proline as a homochiral starting material. The key step was the spirohydantoin ring formation by employing the Bucherer-Bergs reaction of 4-oxoproline derivatives. These structures were determined by NMR studies.
