Friedländer-type condensation of aminonaphthalene carbaldehydes with (1) primary or secondary alcohols mediated by urea/KOH or with (2) diketones or β-ketoesters is described. The behavior of naphthalene derivatives in the Friedländer annulation, resulted in the formation of Friedländer or non-Friedländer products, is also presented. Graphical abstract
摘要描述了通过氨基萘甲醛与(1)由脲/ KOH介导的伯或仲醇或与(2)二酮或β-酮酸酯的弗里德兰德型缩合反应合成苯并喹啉和苯并喹啉酮。还介绍了萘衍生物在Friedländer环空中的行为,导致形成Friedländer或非Friedländer产品。 图形概要
