hydrochloride (DOP·HCl) (2) with N-bromosuccinimide and a nitrating mixture was studied. It was found that bromination of DOP occurred at C-4 and the aromatic ring. Nitration of DOP·HCl produced either 6-nitro- or 6,8-dinitro-deoxypeganines and 6-nitrodeoxyvasicinone or their mixture in various ratios depending on the substrate:nitrating mixture ratio. 6Hand 6-Br-deoxypeganines were transformed into the
研究了脱氧聚乙二醇 (DOP) (1) 及其盐酸盐 (DOP·HCl) (2) 与 N-溴代琥珀酰亚胺和硝化混合物的反应。发现 DOP 的溴化发生在 C-4 和芳环上。DOP·HCl 的硝化产生 6-硝基-或 6,8-二硝基-脱氧花梨醇和 6-硝基脱氧 vasicinone 或它们的混合物,这些混合物的比例取决于底物:硝化混合物的比例。6Hand 6-Br-deoxypeganines 被转化为 4-羟基衍生物、6H(Br) peganols 或 deoxyvasicinones。开发了一种使用 HPTLC 对纯化合物和反应产物混合物进行定性和定量分析的方法。
