2-Oxo-4-phenyl-1,2,5,6,7,8-hexahydroquinoline-3-carbonitrile (10) reacted with hydrazine hydrate, phenylisothiocyanate or benzoyl chloride to give derivatives 12, 13 and 15, respectively. The latter two products were treated with hydrazine hydrate to afford pyrozole[3,4-b]quinolines derivatives 14 and 16, respectively. Compound 10 also reacted with acetonitrile dimer or malononitrile dimer to yield
2-氧代-4-苯基-1,2,5,6,7,8-六氢喹啉-3-甲腈(10)与水合肼、异硫氰酸苯酯或苯甲酰氯反应,分别得到衍生物12、13和15。后两种产物用水合肼处理,分别得到吡唑[3,4-b]喹啉衍生物14和16。化合物10还与乙腈二聚体或丙二腈二聚体反应生成苯并[b][1,8]-萘啶衍生物。对化合物10进行单晶X射线晶体学分析,证实了其结构。
