Aminoketones were trifluoromethylated by using trialkyl(trifluoromethyl)silanes without any reaction promoters. Formation of cyclic intermediates is proposed to be possible transition states in this reaction. Moderate diastereoselectivities were observed in the trifluoromethylation of the aminoketones having a side chain.
氨基酮通过使用三烷基(氟三氟甲基)硅烷在没有任何反应助剂的情况下进行了三氟甲基化。形成环状中间体被提议为此反应中可能的过渡态。在具有侧链的氨基酮的三氟甲基化过程中观察到了适度的抗对映体选择性。
