Efficient One-Pot Synthesis of the 2-Aminocarbonylpyrrolidin-4-ylthio-Containing Side Chain of the New Broad-Spectrum Carbapenem Antibiotic Ertapenem
摘要:
An efficient synthesis of the 2-aminocarbonylpyrrolidin-4-ylthio containing side chain of ertapenem (MK-0826) is described. Starting material N-(O,O-diisopropyl phosphoryl)-trans-4-hydroxy-L-proline is converted in a one-pot process to (2S)-cis-3- [[(4-mercapto-2-pyrrolidinyl)carbonyl] amino] benzoic acid monohydrochloride in 70-75% overall yield via a series of six reactions. The development of each of these reactions and the isolation of the product is discussed in detail.
