our recent achievement, in details, of developing a convenient stereodivergent route for parallel total synthesis of chlorofusin (1) and its all seven chromophore diastereomers (1a–1g) in enantiopure forms, starting from a common racemic azaphilone precursor 10. The newly developed total synthesis shows the great advantages of economy, scalability, stable intermediates, high yields, ease of HPLC-free
氯霉素(1)是少数几个对抗p53-MDM2相互作用的天然拮抗剂之一,是一种天然生物遗传杂种,由27元九环肽和独特的发色团组成,该发色团通过与鸟氨酸的烃键连接。在本文中,我们详细描述了我们最近的成就,即从常见的外消旋氮杂物酮前体开始,开发了一条方便的立体发散路线,用于以对映纯形式并行全合成氯富辛(1)及其所有七个生色团非对映异构体(1a – 1g)。10。新开发的全合成方法显示出经济,可扩展,中间体稳定,收率高,易于进行无HPLC操作和重复的巨大优势。
