CHEMICAL SYNTHESIS
(2RS,4'R,8'R)-a-tocopherol was first synthesized from trimethylhydroquinone and 1,3-dibromophythane. Subsequently, a method for condensing phytyl bromide, prepared from natural phytol, with trimethylhydroquinone in petroleum ether with zinc chloride as the catalyst, was reported. This synthesis was also achieved by directly condensing phytol with trimethylhydroquinone. (Ref. 0001) Synthesis of (2RS,4'R,8'R)-a-tocopherol
