The iterativesynthesis of 2,4,6-triamino-s-triazines (melamines), precursors and dendritic structures, by amination of cyanuric chloride with C-1 versus C-2-substituted 2-aminopropane-1,3-diols (serinols), is comparatively examined. The stereochemistry of the resulting serinolicamino-s-triazines, issued from the restricted rotation about the newly created C(s-triazine)–N bonds, is for the first time
用C -1和C -2-取代的2-氨基丙烷-1,3-二醇(丝氨酸)与C -1取代的氰尿酰氯的胺化反应合成2,4,6- triamino - s -triazines(三聚氰胺),前体和树状结构),经过比较检查。由于基于DNMR和DFT计算的(原)非对映异构性,首次讨论了新产生的C(s-三嗪)-N键的受限旋转所产生的丝氨酸氨基s-三嗪的立体化学。数据。
