Two angular phenothiazines and one angular phenoxazine were successfully synthesized via anhydrous base condensation reaction of 2,6-diamino-4-chloropyrimidine-5-thiol, with 7-chloro-5,8-quinolinequinone,2-aminothiophenol and 2-aminophenol, respectively. Condensation reaction between 2-6-diamino-4-chloropyrimidine-5-thiol and 7-chloro-5,8-quinolinequinone in the presence of anhydrous sodium carbonate
通过2,6-二氨基-4-氯嘧啶-5-硫醇与7-氯-5,8-喹啉醌,2-氨基硫酚和2-氨基酚的无水碱缩合反应成功合成了两个角吩噻嗪和一个角吩恶嗪。在无水碳酸钠存在下2-6-二氨基-4-氯嘧啶-5-硫醇与7-氯-5,8-喹啉醌之间的缩合反应生成10-氨基-8-氯-1,9,11-三氮杂- 5 H-苯并[ a ]吩噻嗪-5- H,1-氮杂5 H-苯并[ a ]吩噻嗪-5-one和1-氮杂5 H在7-氯-5,8-喹啉醌与2-氨基硫酚和2-氨基酚之间分别进行无水碱性缩合制得-苯并[a]吩恶嗪-5-酮。利用Mizoroki-Heck交叉偶联串联反应,通过钯(o)/哌嗪配体将这些角氮杂吩噻嗪-5-酮和角氮杂嗪-5酮转化为它们的衍生物,从而获得六种衍生化的化合物。合成的化合物呈深彩色,并通过结合光谱学和元素分析数据建立了结构阐明。使用计算机和体外筛选方法来研究化合物的抗菌效力。除一种化合物外,所有化合物均与
