METHOD FOR PRODUCING (3-HYDROXYPROPYL)NAPHTHOLS Russian patent published in 2015 - IPC C07C39/14 C07C37/14

Abstract RU 2551655 C1

FIELD: chemistry.

SUBSTANCE: invention refers to a method for the one-stage production of (3-hydroxypropyl)naphthols of having a structure of R¹=CH₂CH₂CH₂OH, R²=OH, R³=H; R¹=OH, R²=CH₂CH₂CH₂OH, R³=H; R¹=OH, R²=CH₂CH₂CH₂OH, R³=CH₂CH₂CH₂OH; R¹=OH, R²=T-Bu, R³=CH₂CH₂CH₂OH, effective biologically active substances of neutropic action. The method consists in conducting a reaction of α-, β-naphthols, their derivatives or their sodium salts with allyl alcohol and alkali at temperature 100-170°C. A purified product yield is 40-60%.

EFFECT: higher yield.
