The present article describes the synthesis of new 4H-1,4-benzothiazines via condensation and oxidative cyclization of substituted 2-aminobenzenethiols with β-diketones/β-ketoesters in dimethyl sulfoxide. The oxidation of these synthesized 4H-1,4-benzothiazines with 30% hydrogen peroxide in glacial acetic acid yielded 4H-1,4-benzothiazine sulfones and the reaction of these synthesized benzothiazines
本文介绍了通过在二甲亚砜中用β-二酮/β-酮酸酯对取代的2-氨基苯硫醇进行缩合和氧化环化反应,合成新的4H-1,4-苯并噻嗪。这些合成的4H-1,4-苯并噻嗪在冰醋酸中用30%过氧化氢氧化可生成4H-1,4-苯并噻嗪砜,并且这些合成的苯并噻嗪与糖(β-D-呋喃核糖-1-乙酸- 2,3,5-三苯甲酸酯)提供了新的呋喃核糖苷。对这些化合物的抗氧化和抗微生物活性进行了评估(使用肉汤微稀释法)。根据元素分析和光谱数据确定合成化合物的结构。
