An alternative synthesis of N 1-(hetero)aryl 3,3,5,5-tetrasubstituted piperazin-2-ones is demonstrated using a copper-mediated Goldberg arylation of a common intermediate in good to fair yields. An improved synthesis of 3,3,5,5-tetramethyl piperazin-2-one is also described. This method allows for the synthesis of substituted piperazin-2-ones which are challenging or inaccessible using traditional Bargellini
N 1-(杂)芳基3,3,5,5-四取代哌嗪-2-酮的替代合成使用铜介导的普通中间体的Goldberg芳基化以良好到公平的产率进行证明。还描述了 3,3,5,5-四甲基哌嗪-2-one 的改进合成。这种方法允许使用传统的 Bargellini 化学合成具有挑战性或无法获得的取代哌嗪-2-酮。
