Novel quinolines fused with a six-member ring 5a–j were prepared in high yields (75–95%) via the Friedlander reaction of dimethoxy-substituted o-aminobenzaldehydes of 3a or 3b with cyclic ketones 4, respectively. The structures of 5a–j were determined by IR, 1H NMR, MS, and elemental analysis. © 2008 Wiley Periodicals, Inc. Heteroatom Chem 19:229–233, 2008; Published online in Wiley InterScience (www
通过 3a 或 3b 的二甲氧基取代的邻氨基苯甲醛分别与环酮 4 的 Friedlander 反应,以高产率(75-95%)制备了与六元环 5a-j 稠合的新型喹啉。5a-j 的结构由红外、1H 核磁共振、质谱和元素分析确定。© 2008 Wiley Periodicals, Inc. 杂原子化学 19:229–233, 2008; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20356
