Synthesis of 4‐thioureidobenzoic acid (2), which on cyclization with ethyl chloroacetate gave 4‐(2‐imino‐5‐oxothiazolidin‐3‐yl)‐benzoic acid (3), which on further reacting with benzoin (4) in the presence of polyphosphoric acid afforded the synthesis of 2‐imino‐3‐(‐1‐oxo‐3,4‐diphenyl‐1H‐isochromen‐6‐yl) thiazolidin‐5‐one (5). Compound 5 was then reacted with substituted anilines to give 6‐(2‐imino
合成4-硫脲基苯甲酸(2),然后用氯乙酸乙酯将其环化,得到4-(2-亚氨基-5-氧噻唑烷-3-基)-苯甲酸(3),其在苯甲酸中进一步与苯偶姻(4)反应多磷酸的存在提供了2-亚氨基3-(-1-氧代-3,4-二苯基-1H-异色素n-6-基)噻唑烷-5-5-1的合成(5)。然后将化合物5与取代的苯胺反应,得到6-(2-亚氨基-5-氧噻唑啉代-3-基)-3,4-二苯基-2-(取代)-异喹啉-1(2H)-1(6)。基于IR 1 HNMR,13 C NMR和元素分析已经阐明了化合物的结构。筛选代表性样品对革兰氏阴性菌大肠杆菌的抗菌活性和铜绿假单胞菌和革兰氏阳性菌,金黄色葡萄球菌,和白喉使用纸片扩散法。J.杂环化学。(2011)。
