Common Name2-methoxy-5a,8,8,11a-tetramethyl-6,7,7a,9,10,11,11b,12-octahydro-5-oxatetraphene-1,4-dione
Description2-Methoxy-5a,8,8,11a-tetramethyl-4,5a,6,7,7a,8,9,10,11,11a,11b,12-dodecahydro-1H-5-oxatetraphene-1,4-dione belongs to the class of organic compounds known as naphthopyrans. Naphthopyrans are compounds containing a pyran ring fused to a naphthalene moiety. Furan is a 6 membered-ring non-aromatic ring with five carbon and one oxygen atoms. Naphthalene is a polycyclic aromatic hydrocarbon made up of two fused benzene rings. 2-methoxy-5a,8,8,11a-tetramethyl-6,7,7a,9,10,11,11b,12-octahydro-5-oxatetraphene-1,4-dione is found in Dactylospongia elegans. 2-Methoxy-5a,8,8,11a-tetramethyl-4,5a,6,7,7a,8,9,10,11,11a,11b,12-dodecahydro-1H-5-oxatetraphene-1,4-dione is an extremely weak basic (essentially neutral) compound (based on its pKa).
