Epoxidation of N-protected homotrop-7-ene (9-azabicyclo[4.2.1]non-7-ene) and 1-substituted derivatives occurs stereoselectively from the exo- (β-) face but a practical alternative approach to the exo- epoxides is based on a serendipitous hydride reduction of a 1-hydroxy-7β,8β-epoxyhomotropane derivative. The epoxidation of 4-aminocyclo-oct-2-enol derivatives occurs with total anti- stereoselectivity
N-保护homotrop -7-烯(9-氮杂二环[4.2.1]壬-7-烯)和1-取代的衍生物的环氧化从立体选择性地发生外(β-)面,但实际的替代方法于-外型-环氧化物基于1-羟基-7β,8β-环氧高碘烷衍生物的偶然氢化物还原。4-氨基环-辛-2-烯醇衍生物发生环氧化,具有完全的抗立体选择性,并为通向内-(α-)7,8-环氧同型环烷开辟了道路。取决于条件,氢化物还原或氢解作用提供了一系列新型的7,8-环氧-或7-羟基-高同环烷和正高同环烷。
