Common Name(2r,2as,4as,7r,7as,7br)-3-formyl-2a,4a,7-trihydroxy-6,6,7b-trimethyl-1h,2h,5h,7h,7ah-cyclobuta[e]inden-2-yl 2,4-dihydroxy-6-methylbenzoate
DescriptionMelledonal belongs to the class of organic compounds known as melleolides and analogues. Melleolides and analogues are compounds with a structure characterized by the presence of a 2-hydroxy-4-methoxy-6-methylbenzoic acid derivative linked to a 3,6,6,7b-tetramethyl-cyclobuta[e]indene moiety. It was first documented in 2009 (PMID: 19795841). Based on a literature review very few articles have been published on Melledonal.
