通过用SeO 2 / H 2 O 2氧化4-氮杂高锰金刚烷5、6,获得并入高金刚烷环系统中的桥连硝酮7、8。这些硝酮与缺电子炔烃的1,3-偶极环加成反应在0°Cr时进行区域特异性反应。t。得到4-取代的异恶唑啉。与苯乙炔的反应需要强制性条件,其中使用偶极亲和剂作为溶剂从7中获得5取代的异恶唑啉9d,并在较高的反应温度下由8直接形成重排吡咯12d。酮硝酮生成的环加合物将8个进一步转化为高金刚烷稠合的吡咯。在这种情况下,通过不同的机理从相同的原料分别获得2-取代的和3-取代的吡咯12a和12e。前者在质子溶剂中通过酰基氮丙啶途径通过热分解而产生,而后者通过烯胺途径在质子溶剂中产生。

Nitrones incorporated in a homoadamantane ring system, which were obtained by SeO2-H2O2 of 4-azahomoadamantane, underwent 1,3-dipolar cycloaddition reaction with electron-deficient alkynes (not with alkenes) to give 4-substituted isoxazoline specifically by steric reasons.
