Synthesis route :
2-acetyl Pyrazine is part of a family of molecules which scent is close to peanuts as well as cooked and roasted fruits. Pyrazines are often obtained with a Gutknecht or Gastaldi condensation reaction, in both cases to condense two amines on two ketones, under the effect of an acid and oxidation.
Here, one of the reagents contains the acetyl group of the final molecule, while the other does not have any branches.
Synthesis precursor :
2-acetyl Pyrazine is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
2-acetyl Pyrazine has no known isomer in perfumery.
