Natural Product Identification

Common Name

7-hydroxy-4'-methoxy-7-methyl-6-oxo-1,4,8,8a-tetrahydrospiro[2-benzopyran-3,2'-oxolan]-8-yl 2,4-dihydroxy-6-methylbenzoate

Description

7-Hydroxy-4'-methoxy-7-methyl-6-oxo-1,4,6,7,8,8a-hexahydrospiro[2-benzopyran-3,2'-oxolane]-8-yl 2,4-dihydroxy-6-methylbenzoate belongs to the class of organic compounds known as p-hydroxybenzoic acid alkyl esters. These are aromatic compounds containing a benzoic acid, which is esterified with an alkyl group and para-substituted with a hydroxyl group. Based on a literature review very few articles have been published on 7-hydroxy-4'-methoxy-7-methyl-6-oxo-1,4,6,7,8,8a-hexahydrospiro[2-benzopyran-3,2'-oxolane]-8-yl 2,4-dihydroxy-6-methylbenzoate.
