Common Name

Eriocalyxin I

Description

Methyl (2E)-2-[(3R,6'R,7'S,8'aS)-6'-ethenyl-2,4-dihydroxy-3',5',6',7',8',8'a-hexahydro-2'H-spiro[indole-3,1'-indolizine]-7'-yl]-3-methoxyprop-2-enoate belongs to the class of organic compounds known as 3-alkylindoles. 3-Alkylindoles are compounds containing an indole moiety that carries an alkyl chain at the 3-position. Eriocalyxin I was first documented in 2023 (PMID: 36893826). Based on a literature review very few articles have been published on methyl (2E)-2-[(3R,6'R,7'S,8'aS)-6'-ethenyl-2,4-dihydroxy-3',5',6',7',8',8'a-hexahydro-2'H-spiro[indole-3,1'-indolizine]-7'-yl]-3-methoxyprop-2-enoate.
