Synthesis of the linear and angular furoquinolin-4-one derivatives 6 and 12 was performed, using nitrobenzofurans 3 and 9 as key intermediates. These compounds were reduced to the corresponding aminobenzofurans 4 and 10, which were condensed in two steps to yield, the linear furoquinolin-4-ones 6a,b and the angular ones 12a,b.
使用硝基苯并呋喃3和9作为关键中间体,合成了线性和角型呋喃喹啉-4-酮衍生物6和12。将这些化合物还原为相应的氨基苯并呋喃4和10,将其分两步进行缩合,得到线性呋喃喹啉-4-酮6a,b和有角呋喃喹啉-4-酮6a ,b。
