Abstract

NEW MATERIAL:Hydroquinone derivatives of formulaI (R1 is lower alkyl, R2, R3 are methyl, methoxy, or incorporate along with other carbon atoms to form benzene ring; R4 is aromatic hydrocarbyl).
EXAMPLE: 2,3,5-Trimethyl-5-(3'-methyl-4'-benzenesulfonyl-2'-butene-1'-yl)-hydroquinone methyl ether.
USE: Synthetic intermediates of vitamin K, coenzyme Q, α-tocopherol.
PREPARATION: The reaction between a compound of formulaII (Y is halogen) and another compound of formulaIII (X is halogen and tosyl) is conducted in the presence of a copper compound as cuprous chloride or LiCuCl2 to form the compound of formulaI. The starting material, the Grignard reagent f formulaII, is obtained by reaction of the corresponding halide and magnesium metal and the compound of formulaIII is prepared by reaction of the sulfonyl chloride of corresponding compound and isoprene in the presence of cuprous halide.
