Fatty amines are commonly prepared from fatty acids; which are themselves obtained from natural sources, typically seed-oils.The overall reaction is sometimes referred to as the Nitrile Process [3] and begins with a reaction between the fatty acid and ammonia at high temperature (>250 °C) and in the presence of a metal oxide catalyst (e.g., alumina or zinc oxide) to give the fatty nitrile.
Diallylamine is a precursor to industrial products. Functionalized allylamines have pharmaceutical applications. Pharmaceutically important allylamines include flunarizine and naftifine; the latter spurred the development of Petasis' borono-Mannich reaction.
