Reaction Steps

(2E,4E,6E,8E)-3,7-dimethyl-9-[2,3,6-trimethyl-4-(trifluoromethoxy)phenyl]-nonatetraen-1-ol (0.6 mmol) could be dissolved in 20 ml. of methylene chloride and added to a suspension of 1.1 g. of activated manganese dioxide in 40 ml. of methylene chloride. After filtration, the filtrate is concentrated to afford (2E,4E,6E,8E)-3,7-dimethyl-9-[2,3,6-trimethyl-4-(trifluoromethoxy)phenyl]-nonatetraen-1-al which is purified by crystallization or chromatography in a conventional manner.
