Natural Product Identification

Common Name

8a-methyl-3-methylidene-octahydrospiro[naphtho[2,3-b]furan-5,2'-oxiran]-2-one

Description

AC1MYZ6A belongs to the class of organic compounds known as eudesmanolides, secoeudesmanolides, and derivatives. These are terpenoids with a structure based on the eudesmanolide (a 3,5a,9-trimethyl-naphtho[1,2-b]furan-2-one derivative) or secoeudesmanolide (a 3,6-dimethyl-5-(pentan-2-yl)-1-benzofuran-2-one derivative) skeleton. 8a-methyl-3-methylidene-octahydrospiro[naphtho[2,3-b]furan-5,2'-oxiran]-2-one is found in Inula racemosa. AC1MYZ6A is an extremely weak basic (essentially neutral) compound (based on its pKa).
