synthesis of 4,5-benzo-1-aza-tricyclo[4.3.1.1(3,8)]undecane (1), a benzo-1-aza-adamantane derivative, is described and features a previously unknown application of the Wolff-Kishner reduction of a nonresonance stabilized or "twisted" amide. An intermediate amino ester is converted to a severely "twisted amide", which, when exposed to hydrazine in alcohol, provides the corresponding "twisted" amino
描述了 4,5-苯并-1-氮杂-三环 [4.3.1.1(3,8)] 十一烷 (1)(一种苯并-1-氮杂-金刚烷衍生物)的合成,其特点是以前未知的 Wolff 应用-非共振稳定或“扭曲”酰胺的 Kishner 还原。中间体氨基酯转化为严重“扭曲的酰胺”,当暴露于醇中的肼时,提供相应的“扭曲”氨基腙。Wolff-Kishner 条件(KOH/乙二醇,200 摄氏度)提供减少的目标 1,而不水解为氨基酸衍生物。这些操作在单个烧瓶中以高产率方便地进行。
