An efficient and mild method has been developed for the amination of β-methoxy amides (γ-lactones) including natural products michelolide, costunolide and parthenolide derivatives by using lithium chloride in good yields. This reaction is applicable to a wide range of substrates with good functional group tolerance. Mechanism studies show that the reactions undergo a LiCl promoted MeOH elimination
已经开发了一种高效温和的方法,用于以良好收率使用氯化锂胺化 β-甲氧基酰胺(γ-内酯),包括天然产物 michelolide、costunolide 和 parthenolide 衍生物。该反应适用于广泛的具有良好官能团耐受性的底物。机理研究表明,反应经历了 LiCl 促进的 MeOH 从底物中消除形成相应的 α,β-不饱和中间体,然后是胺的迈克尔加成。
