Abstract:4-[(Tetrahydro-2H-pyran-2-yl)oxy]phenol was synthesized in 19.2% yield by the reaction of hydroquinone with 3,4-dihydro-2H-pyran catalyzed by PPTS in dichloromethane. The optimum reaction conditions were as follows:the molar ratio of hydroquinone to 3,4-dihydro-2H-pyran 2.5 to 1,reaction temperature 16℃,reaction time 3 h. The structure of the target compound(99.8%)was determined by means of LC-MS and 1H NMR spectra. |
Key words:4-[(tetrahydro-2H-pyran-2-yl)oxy]phenol;PPTS;one step synthesis |
