communication describes the synthesis of substituted 10H-phenothiazines by reaction of 2-aminobenzenethiol 1 and o-halonitrobenzene 2 via Smiles rearrangement. These synthesized phenothiazines are used as base to prepare ribofuranosides by treatment with sugar viz. β -D-ribofuranosyl-1-acetate-2,3,5-tribenzoate. Sulfones are also synthesized by oxidation of 10H-phenothiazines refluxing with H2O2 in glacial
本通讯描述了通过 Smiles 重排使 2-氨基苯硫醇 1 和邻卤硝基苯 2 反应合成取代的 10H-吩噻嗪。这些合成的吩噻嗪用作基础,通过用糖处理制备呋喃核苷。β-D-ribofuranosyl-1-acetate-2,3,5-tribenzoate。砜也可以通过在冰醋酸中用 H2O2 回流氧化 10H-吩噻嗪来合成。所有合成的化合物均已通过 IR、1 H NMR、13 C NMR 质谱和元素分析进行表征,并筛选了抗氧化和抗微生物活性。
