Friedländer synthesis

From Wikipedia, the free encyclopedia

The Friedländer synthesis is the chemical reaction of 2-aminobenzaldehydes[1] with ketones to form quinoline derivatives.[2][3] It is named after German chemist Paul Friedländer (1857-1923).

The Friedländer synthesis

This reaction has been catalyzed by trifluoroacetic acid[4], toluenesulfonic acid[5], iodine[6], and Lewis acids[7].

Several reviews have been published.[8][9][10]
