We developed conditions to carry out the first 'one-pot' Ullmann-Finkelstein-Ullmann multicomponent reaction reported. This reaction allows the one-pot synthesis of dissymmetrical para-disubstituted benzene scaffold from 1-bromo-4-iodobenzene and two N-nucleophiles. CuI/N,N'-dimethyl-cyclohexane-1,2-diamine was used as a catalyst/ligand couple, K3PO4 as a base and the reaction was performed in dioxane. (c) 2006 Elsevier Ltd. All rights reserved.
Synthesis of N-(iodophenyl)-amides via an unprecedented Ullmann–Finkelstein tandem reaction
Using a new Ullmann–Finkelstein tandem reaction, N-(iodophenyl)-amides were synthesized from the corresponding amides and iodo-bromobenzenes. The catalyst/ligand couple CuI/N,N′-dimethyl-cyclohexane-1,2-diamine was used for this reaction in dioxane with K3PO4 as base.
使用新的Ullmann-Finkelstein串联反应,从相应的酰胺和碘代溴代苯合成了N-(碘代苯基)-酰胺。在二恶烷中,以K 3 PO 4为碱,将催化剂/配体对CuI / N,N'-二甲基-环己烷-1,2-二胺用于该反应。
