Gassman Indole Synthesis
The Gassman indole synthesis is a series of chemical reactions used to synthesize substituted indoles from aniline.
This is a one-pot chemical reaction, and none of the intermediates are isolated. R1 can be hydrogen or alkyl, while R2 works best with aryl, but can also be alkyl. Electron-rich anilines, such as 4-methoxyaniline, tend to fail in this reaction.
The 3-position thiomethyl group is often removed using Raney nickel to give the 3-H-indole.

Famous quotes containing the word synthesis:
“It is in this impossibility of attaining to a synthesis of the inner life and the outward that the inferiority of the biographer to the novelist lies. The biographer quite clearly sees Peel, say, seated on his bench while his opponents overwhelm him with perhaps undeserved censure. He sees him motionless, miserable, his head bent on his breast. He asks himself: “What is he thinking?” and he knows nothing.”
—Andre Maurois (1885–1967)
