Ring-opening hydrofluorination of enantiomerically pure (2S,3S)-3-arylglycidyl ethers (aryl = phenyl, 4-trifluoromethylphenyl) by boron trifluoride–diethyl ether under mild conditions provides β-fluoro alcohols in good yield in a stereospecific manner with complete regiocontrol.
在温和条件下,三氟化硼-乙醚在对映体纯的(2 S,3 S)-3-芳基缩水甘油醚(芳基=苯基,4-三氟甲基苯基)上开环氢氟化反应可提供立体定向的高产β-氟代醇完全的区域控制。
