ridazin-3(2H)-ones with 2-formylphenylboronic acid afforded the corresponding biaryl products which were cyclized with ammonia to yield hitherto undescribed pyridazino[4,5-c]isoquinolinones. Removal of the N-benzyl protective group in position 2 yielded the unsubstituted tricyclic pyridazinones.
2-烷基(甲基和苄基)-5-氯-4-甲氧基-和2-烷基(甲基和苄基)-4-氯-5-甲氧基吡啶并-3(2 H)-的Suzuki交叉偶联反应-甲酰基苯基硼酸得到相应的联芳基产物,将其用氨环化以产生迄今未描述的哒嗪并[4,5- c ]异喹啉酮。除去2位上的N-苄基保护基团得到未取代的三环吡啶并酮。
