catalytic synthesis of tetrahydroquinolines via an annulation of N,N-dimethylanilines and maleimides. The reactions utilized the commercially available materials CuFe2O4, tert-butyl hydroperoxide (TBHP) co-oxidant, and acetonitrile solvent. The condition was tolerant of a wide range of functional groups including bromo, ester, cyano, and secondary amine groups. The XRD result of recycled CuFe2O4 particles
在此,我们报告了一种通过N、N-二甲基苯胺和马来酰亚胺的环化来非均相催化合成四氢喹啉的方法。该反应使用市售材料CuFe 2 O 4、叔丁基过氧化氢(TBHP)助氧化剂和乙腈溶剂。该条件耐受广泛的官能团,包括溴、酯、氰基和仲胺基团。回收的CuFe 2 O 4颗粒的XRD结果与新鲜材料相比没有显着差异。
