3-dioxanes (“closed-chain” unit). Issued from the restricted rotation about C(s-triazine)-N(exocyclic) partial double bonds, seen as axes of (pro)diastereomerism, a global four-component rotational equilibrium involving the title compounds is discussed based on DFT computation and (VT) NMR data. Depending on π-deficiency of the s-triazine core, an (un)synchronised deblocking of the generated rotational diastereomers
摘要报道了高度化学选择性制备新的 N-不对称取代的氯二氨基-s-三嗪和三聚氰胺,被视为迭代合成的基础。它由氰尿酰氯与商用 C-2-取代的 2-氨基丙烷-1,3-二醇(“丝氨醇”)胺化组成,起到“开链”单元和对映纯(1S,2S)-2-氨基的作用-1-(4-硝基苯基)丙烷-1,3-二醇(“对硝基苯基丝氨醇”)基于氨基-1,3-二恶烷(“闭链”单元)。从关于 C(s-三嗪)-N(环外)部分双键的受限旋转发出,被视为(原)非对映异构的轴,基于 DFT 计算和(VT)讨论了涉及标题化合物的全局四组分旋转平衡)核磁共振数据。取决于 s-三嗪核的 π 缺陷,观察到生成的旋转非对映异构体的(非)同步解封闭。它们被讨论为内部与内部的影响。分子间NH ... OH(动态)相互作用发生在“开链”单元和“闭链”单元的anancomeric、轴向与赤道、氨基锚定。
