The reaction of methoxynaphthalenes with malonamide in the presence of magnanese(III) acetate gives 2-acetoxy-2-(1-naphthyl)propanediamides and 2-hydroxy-2-(1-naphthyl)propanediamides. It was found that the propanediamidation reaction did occur when naphthalenes have electron-donating substituents, such as a methoxyl group. The reactions of methoxynaphthalenes with ethyl 3-oxobutanoate, 2-cyanoacetamide
在乙酸镁 (III) 存在下甲氧基萘与丙二酰胺反应生成 2-乙酰氧基-2-(1-萘基)丙二酰胺和 2-羟基-2-(1-萘基)丙二酰胺。发现当萘具有给电子取代基(例如甲氧基)时确实会发生丙二酰胺化反应。在乙酸锰 (III) 存在下,甲氧基萘与 3-氧代丁酸乙酯、2-氰基乙酰胺和丙二腈的反应也生成了相应的取代萘,即 2-(乙酰氧基甲基)萘并[2,1-b]呋喃-1-羧酸盐和/或 4-亚甲基-1(4H)-萘酮。讨论了反应机理。
