Common Name

7-[(6-hydroxy-1,2,5,5-tetramethyl-2,3,6,7,8,8a-hexahydronaphthalen-1-yl)methoxy]-6,8-dimethoxychromen-2-one

Description

7-[(6-Hydroxy-1,2,5,5-tetramethyl-1,2,3,5,6,7,8,8a-octahydronaphthalen-1-yl)methoxy]-6,8-dimethoxy-2H-chromen-2-one belongs to the class of organic compounds known as coumarins and derivatives. These are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). 7-[(6-hydroxy-1,2,5,5-tetramethyl-2,3,6,7,8,8a-hexahydronaphthalen-1-yl)methoxy]-6,8-dimethoxychromen-2-one is found in Artemisia tripartita. 7-[(6-Hydroxy-1,2,5,5-tetramethyl-1,2,3,5,6,7,8,8a-octahydronaphthalen-1-yl)methoxy]-6,8-dimethoxy-2H-chromen-2-one is an extremely weak basic (essentially neutral) compound (based on its pKa).
