This paper described a..new convenient synthesis of 2,5-dialkyl-l, 4-benzenediol derivatives starting from non-aromatic compound. 2,5- Dialkyl-1,4-benzenediol derivatives were prepared by the reaction of 2- alkyl-1,4-cyclo-hexanedione with a variety of aldehydes in the presence of lithium chloride in pyridine, and this method was found to be applicable to the synthesis of naturally occurring η-tocopherol in a short route.

Key words: BENZENEDIOL P;CYCLOHEXANEDIONE P;LITHIUM CHLORIDE;ALDEHYDES, CONDENSATION REACTION;tocopherol
