Natural Product Identification
Common Name2-(furan-3-yl)-6a,10b-dimethyl-1h,2h,6h,10ah-naphtho[2,1-c]pyran-4,7,10-trione
Description2-(Furan-3-yl)-6a,10b-dimethyl-1H,2H,4H,6H,6aH,7H,10H,10aH,10bH-naphtho[2,1-c]pyran-4,7,10-trione 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-(furan-3-yl)-6a,10b-dimethyl-1h,2h,6h,10ah-naphtho[2,1-c]pyran-4,7,10-trione is found in Fibraurea tinctoria. 2-(Furan-3-yl)-6a,10b-dimethyl-1H,2H,4H,6H,6aH,7H,10H,10aH,10bH-naphtho[2,1-c]pyran-4,7,10-trione is an extremely weak basic (essentially neutral) compound (based on its pKa).
