Ortho-substituted aryl ketones are prepared from N-[2-(dimethylamino)ethyl]-N-methylbenzamides via ortho lithiation of intermediate α-amino alkoxides, formed in situ by addition of RLi. An ortho lithiation of N-[2-(dimethylamino)ethyl]-N-methylbenzamide is also described.
邻位取代的芳基酮是由N- [2-(二甲基氨基)乙基] -N-甲基苯甲酰胺通过中间体α-氨基醇盐的邻位锂化反应制得的,该中间体是通过添加RLi在原位形成的。还描述了N- [2-(二甲基氨基)乙基] -N-甲基苯甲酰胺的邻位锂化。
