In this study, hexasubstituted thiourea was carried out via reaction of isothiocyanato cyclophosphazene intermediates with a series of aromatics amines and amino acids in a one-pot reaction system. The reaction was not as straightforward as typical thiourea synthesis. Six unexpected thiourea derivatives 3a–f were formed in the presence of cyclotriphosphazene moieties in good yields (53–82%). The structures
在这项研究中,六取代硫脲是通过异硫氰酸根合环磷腈中间体与一系列芳香胺和氨基酸在一锅反应系统中反应进行的。该反应不像典型的硫脲合成那样直接。在环三磷腈部分的存在下,以良好的产率(53-82%)形成了六种意想不到的硫脲衍生物 3a-f。3a-f 的结构通过元素分析和 FTIR、1H、13C 和 31P NMR 光谱表征。讨论了在一锅反应系统中形成反向硫脲的发生。还讨论了合成的硫脲 3a-b 与预测的苯基硫脲 5a-b 和目标 4a 与酶烯酰 ACP 还原酶 (FabI) 的可能结合相互作用。
