A systematic study on the condensation reaction of 2,4-dichlorobenzo[h]quinoline and naphth-1-ylamine in the presence of CuI as catalyst to functionalised mono- and di-substituted (naphthalen-1-yl)benzo[h]quinoline amines was described. Subsequently these mono- and di-substituted amines on polyphosphoric acid catalysed cyclisation reaction with aromatic/heteroaromatic carboxylic acids led to the construction of angular and linear aromatic/heteroaromatic substituted dinaphthonaphthyridines in good yields.
本文系统研究了在 CuI 作为催化剂的条件下,2,4-二氯苯并[h]喹啉和萘-1-基胺的缩合反应,得到了功能化的单取代和二取代(萘-1-基)苯并[h]喹啉胺。随后,这些单取代和二取代胺在多聚磷酸催化下与芳香族/杂芳香族羧酸发生环化反应,得到了角状和线状的芳香族/杂芳香族取代的二萘并[1,2-b:2',1'-e][1,4]二氮杂萘,产率良好。
