A base-promoted amidation of 1-aryl-2,2,2-trifluoroethanones with amines Haller-Bauer reaction has been developed. In this reaction, the direct transformation of 1-aryl-2,2,2-trifluoroethanones into amides 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 this transformation, and several pharmaceutical molecules were synthesized.
已开发出一种碱促进的1-芳基-2,2,2-三氟乙酮与胺的酰胺化反应——哈勒-鲍尔反应。在该反应中,1-芳基-2,2,2-三氟乙酮直接转化为酰胺,C(O)-C键发生断裂,且无需使用任何化学计量的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该转化反应兼容,并合成了几种药物分子。
