Synthesis of (3S, 4S)-4-hydroxy-2, 3, 4, 5-tetrahydropyridazine-3-carboxylic acid, component of luzopeptin A.
摘要:
The enantioselective synthesis of (3S, 4S)4-hydroxy-2, 3, 4, 5-tetrahydropyridazine-3-carboxylic acid 1 is described. The two stereogenic centers in anti relationship are obtained by sequential enantio and chemoselective hydrogenation of beta-ketoester in presence of chiral ruthenium catalyst and diastereoselective amination of beta-hydroxyester with di t-butylazodicarboxylate.
