cascade process occurred to give 9-aminonaphtho[2,3-c]furan-1(3H)-ones in good yields. By using this tandem reaction as a key step, a concise and versatile synthetic strategy for the total synthesis of arylnaphthalene lactone lignans has been developed.
2-炔基苄腈与Reformatsky试剂的串联反应被证明是一种针对1-氨基萘-2-羧酸酯的新颖而有效的方法。有趣的是,以2-(3-羟基丙-1-炔基)苄腈为底物,发生了更复杂的级联过程,以高收率得到了9-氨基萘[2,3-c]呋喃-1(3H)-。通过将该串联反应用作关键步骤,已开发出用于全合成芳基萘内酯木脂素的简洁而通用的合成策略。
