A practical and efficient synthesis of (3R,4S)-1-benzyl4-phenylpyr- rolidine-3-carboxylic acid (1), a key chiral building block for synthesis of biologically active compounds was established by utilizing a stereospecific and regioselective chlorination of in situ generated aziridinium ion, followed by a nitrile anion cyclization. Starting from commercially available (R)-styrene oxide and 3-(benzylamino)propionitrile, the four-step synthesis features a through process without purification of intermediates until isolation of crystalline 1. The robust, chromatography-free and reproducible synthesis of 1 achieved an 84% overall yield from (R)-styrene oxide. This highly efficient process was successfully demonstrated at pilot scale with 17 kg output of 1.

, p. 3265 - 3268 (2007/10/03)
The asymmetric synthesis of 1,3,4-trisubstituted pyrrolidines was accomplished in two steps from readily available starting materials. A 1,3-dipolar cycloaddition of an azomethine ylide to a propiolate ester followed by a Rh-catalyzed asymmetric 1,4-arylation of the resulting pyrroline with an arylboronic acid provided the desired 1,3,4-trisubstituted pyrrolidine products in good to excellent enantioselectivities.
