• 定義

  ChEBI: 9-Fluorenol is a member of the class of hydroxyfluorenes that is 9H-fluorene substituted by a hydroxy group at position 9 (the non-aromatic carbon). It has a role as an animal metabolite. It is a member of hydroxyfluorenes and a secondary alcohol.

• 主な応用

  9-Fluorenol is a wake-promoting agent and is considered a next-generation anti-drowsiness drug. It is also a potential environmental carcinogen.
  9-Fluorenol is a dopamine reuptake inhibitor with IC50 of 9 μM, and a major metabolite of a compound developed as a wakefulness-promoting agent.

• 製造方法

  Synthesis of 9-Fluorenol: A 5-g sample of 9-fluorenone is dissolved in 30 mL of warm ethanol in a 100-mL beaker. To this solution is added, dropwise, 10 mL of a reducing reagent, freshly prepared, which consists of 200 mg sodium methoxide,10 mL methanol, and 0.4 g sodium borohydride.This solution is allowed to stand undisturbed for 10-20 min. A color change is observed as the reaction proceeds from the yellow 9-fluorenone to the white 9-fluorenol.The product is precipitated by the addition of 50 mL of water and neutralized with 0.1 M HCl, vacuum filtered, and washed with cold water to remove any residual inorganic salt formed by the excess of the sodium borohydride reagent and hydrochloric acid.The dried crude product is sufficiently pure for characterization by melting point, infrared spectra,and NMR.The crude product melting point is 153°C, with a product yield of 95-100%.

• 合成

  9-Fluorenol is prepared by reacting 9-fluorenone with THF solution of phosphazene under the action of boron catalyst.Add 9-fluorenone (0.8 mmol), a 0.2 M THF solution of phosphazene (80 μL, 0.016 mmol) and a 0.0762 M THF solution of boron catalyst (420 μL, 0.032 mmol) to a scintillation vial with magnetic stir bar in a glove box. Place the scintillation vial in a Parr reactor. Seal the reactor. Pressurize the reactor with hydrogen gas. Heat reaction mixture at 75°C (inside the reactor). Stir the reaction mixture (1000 rpm) for 20 hours at 75°C. Cool the mixture to room temperature and vent the Parr reactor to obtain 9-hydroxyfluoren. Analyze the reaction mixture by 1H NMR spectroscopy using CDCl3 as solvent.
