87% | With titanium tetrachloride; zinc In tetrahydrofuran at 0 - 90℃; for 2h; Inert atmosphere; Darkness; | 1,1-Bis(4-hydroxyphenyl)-2-hexyloct-1-ene To a suspension of zinc powder (464 mg, 7.10 mmol) in THF (3 mL) at -10 °C was added titanium(IV) chloride (d 1.726, 0.350 mL, 3.18 mmol). The reaction mixture was diluted with THF (1 mL) and then refluxed at 90 °C (bath temperature) for 2 h and then a mixture of 4,4’-dihydroxybenzophenone (360 mg, 1.68 mmol) and 7-tridecanone (104 mg, 0.524mmol) in THF (8 mL) was added to the mixture at 0 °C. After the reaction mixture had been refluxed at 90 °C (bath temperature) for 2 h in the dark, 10% aqueous potassium carbonate was added to the mixture at 0 °C in the light. The mixture was filtered through a short pad of Celite with ethyl acetate, and the filtrate was extracted with ethyl acetate. The organic layer was washed with brine, and dried over sodium sulfate. After filtration of the mixture and evaporation of the solvent, the crude product was purified by thin layer chromatography on silica (eluant; hexane/ethylacetate = 2/1) to afford 1,1-bis(4-hydroxyphenyl)-2-hexyloct-1-ene (177 mg, 89%) as a white solid |

After 2h, tridecan-7-one (6.5g, 32.8 mmol) was slowly added, and the reaction was warmed to ambient temperature. After 1 h, the reaction was heated to reflux. After 4 days, the reaction was cooled, and 1 N HCI (aq) was added to quench the reaction. The reaction was extracted with ethyl acetate (3 x 200 ml_). The combined organic extracts were dried over sodium sulfate, filtered, and concentrated under reduced pressure. The concentrate was purified on silica gel, using ethyl acetate / hexanes as eluent to provide 8.0g of the desired product. TLC (silica gel, 10% ethyl acetate in hexanes): Rf = 0.72. |
