Participants

Reaction Steps

To a solution of 1-(2'-hydroxy-3',4',6'-trimethylphenyl)-1,6-hexanediol (formula III-3 wherein R=H3C, X=H, Y=OH, n=4 in the free form) (0.32 part) in dimethyl formamide (20 volume parts) was added all at once a mixture of Fremy's salt (0.5 part) and potassium biphosphate (0.5 part) in water (50 volume parts). The mixture was stirred for 3 hours at room temperature. The reaction product was taken up with diethyl ether. The diethyl ether layer was washed with water and dried over anhydrous sodium sulfate. The residue upon removal of the solvent was subjected to chromatography on silica gel and eluted with ethyl acetate-diethyl ether (4:1) to give 2,3,5-trimethyl-6-(1',6'-dihydroxyhexyl)-1,4-benzoquinone (formula IV-3 wherein R=H3C, n=4, in the free form) (0.26 part) as a yellow oil.
