were prepared by the reaction of 3-acetyl-2H-cyclohepta[b]furan-2-one with in situ generated enamines from aldehydes and amines. These four 1-acetylazulenes reacted with 2-aminobenzaldehyde and its 4,5-dimethoxy- and 4,5-methylenedioxy-substituted derivatives in the presence of sodium ethoxide to afford twelve 1-(2-quinolyl)azulenes. In a similar manner, three 2-(2-quinolyl)azulenes were also prepared
通过3-乙酰基-2 H-环庚[ b ]呋喃-2-酮与原位生成的烯胺反应,制得1-乙酰基azulene和3-甲基-,3-乙基-和3-丙基取代的1-乙酰基azulenes。从醛和胺中提取。在乙醇钠的存在下,这四个1-乙酰基azulenes与2-氨基苯甲醛及其4,5-二甲氧基和4,5-亚甲基二氧基取代的衍生物反应,得到十二个1-(2-喹啉基)azulenes。以类似的方式,还从2-乙酰基氮杂烯制备了三个2-(2-喹啉基)氮杂烯。
