Description

Methyl (3aR,4S,5R,11aR)-5-(acetyloxy)-10-(hydroxymethyl)-4-{[(2E)-2-methylbut-2-enoyl]oxy}-3-methylidene-2-oxo-2H,3H,3aH,4H,5H,8H,9H,11aH-cyclodeca[b]furan-6-carboxylate belongs to the class of organic compounds known as germacranolides and derivatives. These are sesquiterpene lactones with a structure based on the germacranolide skeleton, characterized by a gamma lactone fused to a 1,7-dimethylcyclodec-1-ene moiety. Melcanthin A is found in Melampodium rosei. Based on a literature review very few articles have been published on methyl (3aR,4S,5R,11aR)-5-(acetyloxy)-10-(hydroxymethyl)-4-{[(2E)-2-methylbut-2-enoyl]oxy}-3-methylidene-2-oxo-2H,3H,3aH,4H,5H,8H,9H,11aH-cyclodeca[b]furan-6-carboxylate.
