Azulene and guaiazulene react with nitroethene to form substitution products having 2-nitroethyl, 2,4-dinitrobutyl, or 2-nitroethenyl groups at the 1(3)-position in low yields. The presence of formic acid prevented the formation of the dinitrobutyl compound, and increased the yield of the 2-nitroethyl derivative. A reaction course leading to these products is proposed. Reduction of 1-(2-nitroethyl)azulene
Azulene 和 guaiazulene 与硝基乙烯反应以低产率形成在 1(3)-位具有 2-硝基乙基、2,4-二硝基丁基或 2-硝基乙烯基的取代产物。甲酸的存在阻止了二硝基丁基化合物的形成,并增加了 2-硝基乙基衍生物的产率。提出了导致这些产物的反应过程。1-(2-硝基乙基)芴和1-(2-硝基乙基)愈创甘油的还原以良好的产率得到相应的胺化合物。这种两步法为具有伯氨基的 2-(1-azulenyl) 乙胺提供了一种新的、改进的途径。胺产品,像相关的生物胺一样,抑制平滑肌的收缩。
