Abstract:The key intermediate of Teneligliptin, (2S)-4-oxo-2-(3-thiazolidinylcarbonyl)-1-pyrrolidinecarboxylic acid tert-butyl ester, was synthesized from trans-4-hydroxy-L-proline and cysteamine hydrochloride in three steps including amino protection, oxidation, condensation. The overall yield from this synthetic route was 73.8%. The new strategy used in this method had the advantages including less pollution, lower corrosion, and high yield. It was suitable for industrial application. At the same time, we discussed and optimized the oxidation method. The structure was confirmed by 1H NMR and ESI-MS.
Key words:intermediate of Teneligliptin; 4-hydroxy-L-proline; oxidation; (2S)-4-oxo-2-(3-thiazolidinylcarbonyl)-1-pyrrolidinecarboxylic acid tert-butyl ester
