Synthesis of alkyl/aryl [2-(1,2,4,5-tetrahydro-3-sulfanylene/selenylene naphtha[1,8-f,g][1,5,3]diazaphosphocin-3-yl) methyl amino acid esters] () was accomplished in three steps. 1, 8-diamino naphthalene () was reacted with tris (bromomethyl) phosphine () in the presence of triethylamine in dry tetrahydrofuran (THF) under N2 atmosphere to form a PIII intermediate (3). It was converted to the corresponding
烷基/芳基[2-(1,2,4,5-四氢-3-亚硫烷基/亚硒基石脑油[1,8- f,g ] [1,5,3]二氮杂膦-3-基)甲基氨基酸的合成酯]()分三个步骤完成。1,8-二氨基萘()与三(溴甲基)膦(在三乙胺存在下,在无水四氢呋喃(THF)中,在N 2气氛下形成P III中间体(3)。通过分别与硫和硒反应,将其转化为相应的硫化物(4)和硒化物(5)。中间体4和5与氨基酸酯进一步反应,得到标题化合物()。通过元素分析和光谱数据(IR,1 H,13 C,31 P NMR和FAB质量)建立标题化合物的结构。对这些化合物的抗微生物活性进行了评估,并显示出显着的活性。J.杂环化学。(2010)。
