Common Name(2r,3r,4r,5s)-3,4-dimethyl-2,5-bis(3,4,5-trimethoxyphenyl)oxolane
DescriptionEpigrandisin belongs to the class of organic compounds known as 7,7'-epoxylignans. These are lignans with a structure based on a 2,5-diaryl-3, 4-dimethyltetrahydrofuran skeleton. (2r,3r,4r,5s)-3,4-dimethyl-2,5-bis(3,4,5-trimethoxyphenyl)oxolane is found in Aglaia leptantha, Bonamia spectabilis, Rhaphidophora decursiva and Saururus chinensis. (2r,3r,4r,5s)-3,4-dimethyl-2,5-bis(3,4,5-trimethoxyphenyl)oxolane was first documented in 2000 (PMID: 10843571). Based on a literature review very few articles have been published on epigrandisin (PMID: 11421741).
