hydroxyl in one methano bridge and a variety of syn- or anti-chloro, fluoro, hydroxy, methyl, or phenyl substituents in the other methano bridge have been effected. Rearrangements of iodides to alcohols were initiated using Selectfluor. Rearrangement of alcohols to fluorides was initiated using Deoxo-Fluor. Ring opening of 2-azabicyclo[2.2.0]hex-5-ene exo-epoxide with organocopper reagents is regioselective
立体选择性合成新颖的5,6-二官能化的-2-氮杂双环[2.1.1]己烷,在一个甲氧基桥中含有5-抗氟或羟基,以及多种顺式或反式氯,氟,羟基,甲基或苯基另一个甲醇桥中的取代基已经实现。使用Selectfluor可以将碘化物重排为醇。使用Deoxo-Fluor将醇重排为氟化物。用有机铜试剂将2-氮杂双环[2.2.0]己-5-烯外环氧化物的开环在C(5)上是区域选择性的。
