Fischer synthesis

http://large.stanford.edu/courses/2015/ph240/dodaro1/ The Fischer indole synthesis is a chemical reaction that produces the aromatic heterocycle indole from a (substituted) phenylhydrazine and an aldehyde or ketone under acidic conditions. The reaction was discovered in 1883 by Emil Fischer. Today antimigraine drugs of the triptan class are often synthesized by this method. This reaction can be catalyzed by Brønsted acids such as HCl, H2SO4, polypho…
