将不同的模型化合物应用于与盐酸胍的分步生长缩合反应中,以探索三胺和寡胺在幻影合环缩合聚合过程中的适用范围。用APCI质谱、不同的一维和二维同核、异核耦合核磁共振技术证明了五元环的选择性形成,并通过量子化学计算对其进行了研究。此外,还排除了盐酸胍和仲胺之间发生环合反应的可能性。得到的低聚物进行了抗菌试验,对大肠杆菌表现出中等的活性。
Different model compounds were applied in step-growth condensation reactions with guanidine hydrochloride in order to explore the scope of tri- and oligoamine applicability for phantom ring-closing condensation polymerization processes. The selective formation of five-membered rings was proven by APCI mass spectrometry, different one- and two-dimensional homo- and heteronuclear coupling NMR techniques and investigated via quantum chemical calculations. Furthermore the possibility of ring-closing reactions among guanidine hydrochloride and merely secondary amines was precluded. The obtained oligomers were exposed to antibacterial tests and exhibited a moderate activity towards Escherichia coli.
