Reaction Steps

Alpha-myrcene (6-methylene-2-methylocta-1,7-diene) is chlorinated to 2-chloromethyl-6-methyleneocta-1,7-diene. This is reacted with dimethyloctyl magnesium chloride to produce 3,7-dimethylene-11,15-dimethylhexadec-1-ene. This compound yields 7-methylene-3,11,15-trimethylhexadec-2-en-1-ol which, when reacted with TMHQ and hydrogenated, produces Vitamin E.
