Common Name

xi-3,6-Dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran

Description

xi-3,6-Dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran, also known as 4-methyl-2-(2-methyl-1-propen-1-yl)-3,6-dihydro-2H-pyran or neryl oxide, belongs to the class of organic compounds known as pyrans. Pyrans are compounds containing a pyran ring, which is a six-member heterocyclic, non-aromatic ring with five carbon atoms, one oxygen atom and two ring double bonds. xi-3,6-Dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran is a celery, cortex, and diphenyl oxide tasting compound. xi-3,6-Dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran has been detected, but not quantified in, a few different foods, such as black elderberries (Sambucus nigra), gingers (Zingiber officinale), and white wine. This could make XI-3,6-dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran a potential biomarker for the consumption of these foods. xi-3,6-Dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on xi-3,6-Dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran.
