Common Name

methyl 8-ethyl-9-hydroxy-2,4,4,7-tetramethyl-3,5,10-trioxonaphtho[2,3-b]pyran-2-carboxylate

Description

Methyl 8-ethyl-9-hydroxy-2,4,4,7-tetramethyl-3,5,10-trioxo-2H,3H,4H,5H,10H-naphtho[2,3-b]pyran-2-carboxylate belongs to the class of organic compounds known as naphthopyranones. Naphthopyranones are compounds containing a naphthopyran skeleton where a ring carbon bears a carboxylic acid group. Naphthtopyran is made up of the pyran ring fused to a naphthalene ring system. methyl 8-ethyl-9-hydroxy-2,4,4,7-tetramethyl-3,5,10-trioxonaphtho[2,3-b]pyran-2-carboxylate is found in Garveia annulata. Methyl 8-ethyl-9-hydroxy-2,4,4,7-tetramethyl-3,5,10-trioxo-2H,3H,4H,5H,10H-naphtho[2,3-b]pyran-2-carboxylate is an extremely weak basic (essentially neutral) compound (based on its pKa).
