Common Name

7-hydroxy-5-[(2s,3s)-3-hydroxybutan-2-yl]-6,8-dimethyl-3-(6-methyl-4-oxo-5,6-dihydropyran-2-yl)chromen-2-one

Description

7-Hydroxy-5-[(2S,3S)-3-hydroxybutan-2-yl]-6,8-dimethyl-3-(2-methyl-4-oxo-3,4-dihydro-2H-pyran-6-yl)-2H-chromen-2-one belongs to the class of organic compounds known as 7-hydroxycoumarins. These are coumarins that contain one or more hydroxyl groups attached to the C7 position the coumarin skeleton. Based on a literature review very few articles have been published on 7-hydroxy-5-[(2S,3S)-3-hydroxybutan-2-yl]-6,8-dimethyl-3-(2-methyl-4-oxo-3,4-dihydro-2H-pyran-6-yl)-2H-chromen-2-one.
