1,4-Functionalisation of cycloocta-1,3-diene using a nitroso-cycloaddition strategy is followed by intramolecular displacement by nitrogen to yield the 9-methyl-9-azabicyclo[4.2.1]nonane (homotropane) and -non-7-ene (homotrop-7-ene) systems and N-benzyl derivatives. The approach can be adapted to allow access to 1-methylhomotropanes and -7-enes via transannular amidomercuration/de-mercuration.
使用亚硝基环加成策略对环辛-1,3-二烯进行1,4-官能化,然后通过氮进行分子内置换,得到9-甲基-9-氮杂双环[4.2.1]壬烷(均烷)和-non-7 -烯(同型7-烯)系统和N-苄基衍生物。该方法可适于允许通过环戊酰胺酰胺化/去汞化反应获得1-甲基同环戊烷和-7-烯。
