Common Name

(2s,4'r,12'r)-4,6,8'-trihydroxy-4',12'-bis(4-hydroxyphenyl)-4'-methoxy-5',13'-dioxaspiro[1-benzofuran-2,3'-tricyclo[7.4.0.0²,⁶]tridecane]-1',6',8'-trien-3-one

Description

(2S,2'R)-2'beta,8'alpha-Bis(4-hydroxyphenyl)-4,5',6-trihydroxy-8'-methoxy-3',4'-dihydrospiro[benzofuran-2(3H),9'(8'H)-[2H]furo[2,3-h][1]benzopyran]-3-one belongs to the class of organic compounds known as 2-arylbenzofuran flavonoids. These are phenylpropanoids containing the 2-phenylbenzofuran moiety. (2s,4'r,12'r)-4,6,8'-trihydroxy-4',12'-bis(4-hydroxyphenyl)-4'-methoxy-5',13'-dioxaspiro[1-benzofuran-2,3'-tricyclo[7.4.0.0²,⁶]tridecane]-1',6',8'-trien-3-one is found in Daphne feddei. Based on a literature review very few articles have been published on (2S,2'R)-2'beta,8'alpha-Bis(4-hydroxyphenyl)-4,5',6-trihydroxy-8'-methoxy-3',4'-dihydrospiro[benzofuran-2(3H),9'(8'H)-[2H]furo[2,3-h][1]benzopyran]-3-one.
