The facile general synthetic route to azidoalkylphosphonates by the nucleophilic substitution reaction in a series of bromoalkylphosphonates was elaborated, using 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) as a recyclable reaction medium. These azidoalkylphosphonates were used as intermediates for copper(I)-catalyzed regioselective 1,3-dipolar cycloaddition with a variety of alkynes
使用 1-丁基-3-甲基咪唑鎓六氟磷酸盐 ([bmim][PF6]) 作为可回收的反应介质,详细阐述了通过一系列溴代烷基膦酸酯的亲核取代反应合成叠氮烷基膦酸酯的简便通用途径。这些叠氮烷基膦酸酯被用作铜(I)催化的区域选择性 1,3-偶极环加成与各种炔烃的中间体,得到 4-取代的(1H-1,2,3-三唑-1-基)烷基膦酸酯作为潜在的候选药物. © 2008 Wiley Periodicals, Inc. 杂原子化学 19:293–300, 2008; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20420
