Reaction of 1,3,3-trihalo-7-oxabicyclo[4.1.0]heptanes with boron trifluorideâether or HF· pyridine resulted in the regio-and stereo-selective formation in high yield of the corresponding cis-fluorohydrins; using a succession of cyclisations followed by ring-opening reactions by fluoride afforded an iterative preparation of unknown 2,2,6,6-tetrafluorocyclohexanol 13 starting from the chlorinated analogue 1.
将 1,3,3-三卤-7-氧杂双环[4.1.0]庚烷与三氟化硼乙醚或 HFÂ-吡啶反应,可高产率地形成相应的顺式氟化氢,并具有区域和立体选择性;通过连续的环化反应以及氟化开环反应,可从氯化类似物 1 开始,迭代制备出未知的 2,2,6,6-四氟环己醇 13。
