Application
Mukaiyama Oxidation-Reduction Condensation
[Experimental procedure]
to a mixture of alkoxydiphenylphosphine (2, 0.60 mmol), prepared from the alcohol (1), n-BuLi and chlorodiphenylphosphine, and tetrafluoro-1,4-benzoquinone (0.72 mmol) under argon atmosphere is added a dichloromethane (0.50 mL) solution of alcohol (3, 0.72 mmol) at room temperature. After the reaction that is monitored by TLC was completed, the reaction mixture is quenched by adding water and the aqueous layer is extracted with dichloromethane. The organic layers are dried over anhydrous sodium sulfate. After filtration and evaporation, the resulted residue is purified by preparative TLC to afford the corresponding ether (4).
