synthesized from reactions of 2-cyclohexylaminomethyl-4-t-butylphenol I [8c] with various dichlorophosphinyl carbamates (III) [8a-b] in dry toluene in the presence of triethylamine at 40-50 °C. All the title compounds (IVa-j) at reflux temperature are degraded to 2-amino-6-(1,1-dimethylethyl)-3-cyclohexyl-3,4-dihydro-2H-1,3,2-benzoxazaphosphorine-2-oxide (IVk) exclusively. The structures are determined
新型2-烷基/芳基氨基甲酸-6-(1,1-二甲基乙基)-3-环己基-3,4-二氢-2 H -1,3,2-苯并恶唑-膦-2-氧化物(IV)的合成在三乙胺存在下于40-50°C下,在干燥的甲苯中,将2-环己基氨基甲基-4-叔丁基苯酚I [8c]与各种二氯膦基氨基甲酸酯(III)[8a-b]反应。在回流温度下,所有标题化合物(IVa-j)均被降解为2-氨基-6-(1,1-二甲基乙基)-3-环己基-3,4-二氢-2 H -1,3,2-苯并氮杂磷酰基-专门用于2氧化物(IVk)。通过红外,核磁共振和质谱研究确定结构。对他们进行了抗真菌活性筛选黑青霉,黑曲霉和Helminthosporium sps,以及对大肠杆菌,金黄色葡萄球菌和铜绿假单胞菌的抗菌活性。其中一些具有重要的活动。
