Definition
ChEBI: Menthofuran is a monoterpenoid that is 4,5,6,7-tetrahydro-1-benzofuran substituted by methyl groups at positions 3 and 6. It has a role as a nematicide and a plant metabolite. It is a member of 1-benzofurans and a monoterpenoid.
Preparation
(+)-Menthofuran [17957-94-7] is isolated fromMentha oils or is prepared synthetically, for example, by treatment of (+)-pulegone with fuming sulfuric acid in acetic anhydride and pyrolysis of the resulting sultone.
Taste threshold values
Taste characteristics at 10 ppm: musty, nutty, coffee, raw and legume
Synthesis Reference(s)
The Journal of Organic Chemistry, 48, p. 2442, 1983 DOI: 10.1021/jo00162a037
Synthesis
By thermal decomposition of the sulfone of 3-hydroxy-3,8(9)-methadiene-9-sulfonic acid; the latter is obtained by sulfonapulegone in acetic anhydride.
