Reaction of 3‐(3‐cyanopropylthio)[1]benzothiophene‐2‐carbonitrile with tert‐BuONa gave 5‐amino‐1,2‐dihydro[1]benzothieno[3,2‐d]thieno[2,3‐b]pyridine and 5‐amino‐2,3‐dihydro[1]benzothieno[3,2‐b]thiepin‐4‐carbonitrile. The latter compound served as a convenient scaffold for the synthesis of the new heterocycles, [1]benzothieno[3′,2′:2,3]thiepino[4,5‐d]pyrimidines. All of our new tetracyclic products
3-(3-氰基丙硫基)[1]苯并噻吩-2-腈与叔-BuONa的反应得到5-氨基1,2-二氢[1]苯并噻吩并[ 3,2- d ]噻吩并[2,3- b ]吡啶和5-氨基-2,3-二氢[1]苯并噻吩并[3,2 - b ]噻吩-4-碳腈。后一种化合物用作合成新杂环[1]苯并噻吩并[3',2':2,3]噻吩并[4,5- d ]嘧啶的便利骨架。我们对所有新的四环产物的戊糖苷的体外抑制活性进行了评估,戊糖苷是代表性的高级糖基化终产物之一。
