Abstract
Abstractmagnified imageA study on interaction between N‐(4‐pyridinyliden)anilines 1‐4 and 2,2‐dimethoxypropane under Kametani reaction conditions was realized. According to the GC‐MS analysis of crude reaction, besides the needed 4‐methyl‐2‐(4‐pyridinyl)quinolines 5‐8, three collateral products: secondary amines 9‐12, 4‐(2‐methylprop‐1‐enyl)quinolines 13‐16 and 4‐(2‐methoxy‐2‐methylpropyl)quinolines 17‐20 were formed. Unexpected quinolines 13‐16 as well the desired quinolines 5‐8 were isolated and fully characterized. In contrast, a condensation of N‐benzylidenaniline 21 with 2,2‐dimethoxypropane afforded a set of different quinoline products.
