Common Name

5,7-dihydroxy-9-methyl-3-methylidene-2-oxo-4,5,6a,7,9a,9b-hexahydro-3ah-spiro[azuleno[4,5-b]furan-6,2'-oxiran]-4-yl 2-[(acetyloxy)methyl]but-2-enoate

Description

5,7-Dihydroxy-9-methyl-3-methylidene-2-oxo-3,3a,4,5,6a,7,9a,9b-octahydro-2H-spiro[azuleno[4,5-b]furan-6,2'-oxirane]-4-yl 2-[(acetyloxy)methyl]but-2-enoate belongs to the class of organic compounds known as guaianolides and derivatives. These are diterpene lactones with a structure characterized by the presence of a gamma-lactone fused to a guaiane, forming 3,6,9-trimethyl-azuleno[4,5-b]furan-2-one or a derivative. 5,7-dihydroxy-9-methyl-3-methylidene-2-oxo-4,5,6a,7,9a,9b-hexahydro-3ah-spiro[azuleno[4,5-b]furan-6,2'-oxiran]-4-yl 2-[(acetyloxy)methyl]but-2-enoate is found in Stylotrichium rotundifolium. 5,7-Dihydroxy-9-methyl-3-methylidene-2-oxo-3,3a,4,5,6a,7,9a,9b-octahydro-2H-spiro[azuleno[4,5-b]furan-6,2'-oxirane]-4-yl 2-[(acetyloxy)methyl]but-2-enoate is an extremely weak basic (essentially neutral) compound (based on its pKa).
