Abstract

NEW MATERIAL:Hydroquinone compounds of formula I [R1 is lower alkyl, methoxymethyl; R2,R3 are methyl, methoxy, or may be form benzene ring with directly connecting carbons; R4 is aromatic hydrocarbyl that may be substituted; n is 1W11].
EXAMPLE: The compound of formula II.
USE: Synthetic intermediates of drugs as vitamin k, coenzyme Q, α-tocopherol, etc.
PREPARATION: The condensation reaction between a compound of formula III and a prenyl derivative of formula IV (X is halogen, tosyl) is effected in the presence of a basic compound to produce the objective compound of formula I.
