A base-promoted amidation of 1-aryl-2,2,2-trifluoroethanones with amines via Haller-Bauer reaction has been developed. In this reaction, the direct transformation of 1-aryl-2,2,2-trifluoroethanones into amides via C(O)-C bond cleavage occurs without the use of any stoichiometric chemical oxidants or transition-metal catalysts. A series of primary and secondary amines are shown to be compatible with
通过 Haller-Bauer 反应开发了一种碱促进的 1-aryl-2,2,2-三氟乙酮与胺的酰胺化反应。在此反应中,1-芳基-2,2,2-三氟乙酮通过 C(O)-C 键断裂直接转化为酰胺,无需使用任何化学计量化学氧化剂或过渡金属催化剂。一系列伯胺和仲胺被证明与这种转化相容,并且合成了几种药物分子。
