用途有機合成原料。

説明5H-5-Methyl-6,7-dihydrocyclopenta(-b)pyrazine has an earthy, baked potato, peanut, roasted odor. It may be prepared from condensation of 2-hydroxy-3-methyl-2-cyclopentene-l-one and ethylene diamine; by condensing a cyclopentenolone with alkylenediamines, or alternatively, an aliphatic α-diketone with 1,2-diamino cyclopentane; the resulting product is dehydrogenated in the presence of palladium over activated charcoal or copper chromite.
