Common Name3-methyl-5-(6-methylhept-6-en-2-yl)-8-methylidene-3a,4,5,6,7,8a-hexahydro-1h-azulen-4-ol
Description3-Methyl-5-(6-methylhept-6-en-2-yl)-8-methylidene-1,3a,4,5,6,7,8,8a-octahydroazulen-4-ol belongs to the class of organic compounds known as pachydictyane and cneorubin diterpenoids. These are diterpenoids with a structure that is based either on the pachydictyane or the cneorubin skeleton. Pachydictyane is a bicyclic compound consisting of a guaiane skeleton that carries a prenyl group attached to the C12 carbon atom. Cneorubin is a tricyclic compound consisting of a cycloprop[e]azulene where the cyclopropane carries a methyl group and a 4-methylpentyl group. 3-methyl-5-(6-methylhept-6-en-2-yl)-8-methylidene-3a,4,5,6,7,8a-hexahydro-1h-azulen-4-ol is found in Dictyota dichotoma. 3-Methyl-5-(6-methylhept-6-en-2-yl)-8-methylidene-1,3a,4,5,6,7,8,8a-octahydroazulen-4-ol is an extremely weak basic (essentially neutral) compound (based on its pKa).
