Hydrochloric Acid → (6Z,16Z)-12-((Z)-dec-4-enyl)docosa-6,16-dien-11-ol

참여 물질

반응 단계

To a suspension of magnesium turnings (0.6 g, 23.9 mmol) in tetrahydrofuran (5 mL) was slowly added a solution of (Z)-1-bromodec-4-ene 3 (4.5 g, 20.5 mmol) in tetrahydrofuran (5 mL). The reaction mixture was stirred for 30 minutes at room temperature then a solution of (Z)-2-((Z)-dec-4-enyl)dodec-6-enal 7 in tetrahydrofuran (5 mL) was added. The solution was stirred for 15 minutes at room temperature then poured into 5% hydrochloric acid (50 mL) and ice (100 mL). The solution was extracted with ether (2×150 mL). The combine ether extracts were dried on magnesium sulfate, filtered, and concentrated in vacuo to dryness. The residue was purified by column chromatography (1% ethyl acetate in hexanes) to afford (6Z,16Z)-12-((Z)-dec-4-enyl)docosa-6,16-dien-11-ol 8 as a colorless oil (4.8 g, 76%). Rf 0.45 (10% EtOAc-Hexanes).
