Application of Pd-catalysed amines arylation for the synthesis of benzopolyazamacrocycles
摘要:
Amination of 1,2- or 1,3-dihalobenzenes by linear polyamines in the presence of Pd(dba)(2)/BINAP catalytic system can serve as a convenient one-pot procedure for the synthesis of benzopolyazamacrocycles. (C) 2003 Elsevier Science Ltd. All rights reserved.
The synthesis of a new family of polyaza- and polyoxapolyazamacrocycles by a simple and efficient one-pot palladium-catalyzed diamination of 1,3-dibromobenzene is described. The dependence of the nature of the starting polyamines on the yield of the products is demonstrated. The synthesis of N α ,N Ï -bis(3-bromophenyl)-substituted polyamines is elaborated to obtain intermediates for the synthesis of polyazamacrocycles consisting of two polyamine and two benzene fragments (cyclodimers). The formation of tri- and tetraarylated polyamines is studied and regularities of the process are established. The synthesis of 1,3-bis(polyamino)-substituted benzenes is also described.
本文介绍了通过简单高效的钯催化 1,3-二溴苯二胺化一锅法合成一系列新的多氮杂环和多氧杂氮杂环的过程。证明了起始多胺的性质对产物产量的影响。详细阐述了 N δ±,N Ï -双(3-溴苯基)取代多胺的合成,以获得合成由两个多胺和两个苯片段(环二聚体)组成的多氮杂环的中间体。研究了三芳基化和四芳基化多胺的形成,并确定了这一过程的规律性。此外,还介绍了 1,3-双(多氨基)取代苯的合成。
