Abstract

NEW MATERIAL:A hydroquinone derivative of formula I [R1 is -CH2OCH2CH2 OCH3; R2, R3 are CH3O or together form -CH=CH-CH=CH-; R4 is (substituted) aromatic hydrocarbon].
EXAMPLE: 2, 3-Dimethoxy-5-methyl-6-( 3'-methyl- 4' -benzenesulfonyl- 2' -buten-1'- yl)-hydroquinone dimethoxyethoxymethyl ether.
USE: Synthetic intermediate for coenzyme Q or vitamin K2. The compound can be easily prepared, and is stable to acid and salt.
PROCESS: The compound I is prepared by reacting a Grignard compound of formula II with a compound of formula III (X is halogen or tosyl) in the presence of a copper compound catalyst such as cuprous halide.
