Description

1-{2'-Formyl-4-methoxy-4'-methyl-3,6'-dioxo-3H-spiro[1-benzofuran-2,1'-cyclohexane]-2',4'-dien-5-yl}-3-methylbutyl acetate belongs to the class of organic compounds known as benzofurans. These are organic compounds containing a benzene ring fused to a furan. Furan is a five-membered aromatic ring with four carbon atoms and one oxygen atom. Purpactin C is found in Penicillium and Talaromyces purpureogenus. Purpactin C was first documented in 1991 (PMID: 2010354). Based on a literature review very few articles have been published on 1-{2'-formyl-4-methoxy-4'-methyl-3,6'-dioxo-3H-spiro[1-benzofuran-2,1'-cyclohexane]-2',4'-dien-5-yl}-3-methylbutyl acetate.
