(3ar,4r,8s,11ar)-8-hydroxy-6,10-dimethyl-3-methylidene-2-oxo-3ah,4h,5h,8h,9h,11ah-cyclodeca[b]furan-4-yl (2r,3r)-2,3-dimethyloxirane-2-carboxylate

Description

MOLLISORIN B 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. (3ar,4r,8s,11ar)-8-hydroxy-6,10-dimethyl-3-methylidene-2-oxo-3ah,4h,5h,8h,9h,11ah-cyclodeca[b]furan-4-yl (2r,3r)-2,3-dimethyloxirane-2-carboxylate is found in Helianthus gracilentus. (3ar,4r,8s,11ar)-8-hydroxy-6,10-dimethyl-3-methylidene-2-oxo-3ah,4h,5h,8h,9h,11ah-cyclodeca[b]furan-4-yl (2r,3r)-2,3-dimethyloxirane-2-carboxylate was first documented in 2004 (PMID: 15104494). Based on a literature review very few articles have been published on MOLLISORIN B.
