Copper-Catalyzed Carboxamide-Directed Ortho Amination of Anilines with Alkylamines at Room Temperature
摘要:
In this report, a highly efficient method for the room temperature installation of alkyl amino motifs onto the ortho position of anilines via Cu-catalyzed carboxamide-directed amination with alkylamines is described. This method offers a practical solution for the rapid synthesis of complex arylamines from simple starting materials and enables new planning strategies for the construction of arylamine-containing pharmacophores. A single electron transfer (SET)-mediated mechanism is proposed.

for synthesis of amides and hydroxamicacids from nitroarenes and aldehydes is described. The MnO2 catalyzed thermal deoxygenation of nitrobenzene resulted in formation of a reactive nitroso intermediate which on reaction with aldehydes provided amides and hydroxamicacids. The thermal neat reaction in the presence of 0.01 mmol KOH predominantly led to formation of hydroxamicacid whereas reaction
