- Friedländer synthesis
The Friedländer synthesis is the
chemical reaction of 2-aminobenzaldehydes [Organic Syntheses , Coll. Vol. 3, p.56 (1955); Vol. 28, p.11 (1948). ( [http://www.orgsyn.org/orgsyn/prep.asp?prep=cv3p0056 Article] )] withketone s to formquinoline derivatives. [Friedländer, P. "Ber. " 1882, "15", 2572.] [Friedländer, P.; Gohring, C. F. "Ber. " 1883, "16", 1833.] It is named after German chemist Paul Friedländer (1857-1923).This reaction has been catalyzed by
