diastereoselective multicomponent one-pot synthesis of a series of pharmaceutically interesting functionalized piperidine derivatives has been developed based on a low-cost and environmentally benign Bi(NO3)3·5H2O catalyst via tandem reactions of 1,3-dicarbonyl compounds, aromatic aldehydes, and various amines in ethanol at room temperature. High atom-economy, good yields, eco-friendliness, and mild reaction conditions
基于低成本和环境友好的Bi(NO 3)3 ·5H 2 O催化剂,通过串联反应进行了简单,直接和高效的非对映选择性多组分一锅合成一系列可药用的功能化哌啶衍生物。室温下在乙醇中的1,3-二羰基化合物,芳族醛和各种胺。高原子经济性,良好的产率,生态友好性和温和的反应条件是该方案的一些重要特征。
