Tetrabutylammonium tribromide (TBATB) has been found to be an efficient catalyst for the one-pot synthesis of highly substituted piperidines through a combination of 1,3-dicarbonyl compounds, aromatic aldehydes, and various amines in ethanol at room temperature. Atom economy, good yields, environmentally benign, and mild reaction conditions are some of the important features of this protocol.
已发现三溴化四丁基铵(TBATB)是在室温下通过乙醇中1,3-二羰基化合物,芳族醛和各种胺的组合,一锅法合成高度取代的哌啶的有效催化剂。原子经济,产率高,环境友好,反应条件温和是该协议的一些重要特征。
