Tandem Michael addition product 5 provides a template for azanorbornane derivatives that display potent substance P receptor affinity. The advantages of this synthesis include: the straightforward preparation of both syn and anti azanorbornane diastereomers, access to two, and perhaps more, substituents at C-2 (a and b series), and the straightforward functionalization of the amine at C-3. Mechanistic
串联迈克尔加成产物5提供了显示有效物质P受体亲和力的金刚烷烷衍生物的模板。这种合成的优点包括:直接合成顺式和反式金刚烷硼烷非对映异构体,在C-2(a和b系列)获得两个,也许还有更多取代基,以及在C-3上胺的直接官能化。机理研究表明,第二次1,4-加成通过亚硝酸盐和酯的顺式加成而动力学进行。文献中有矛盾的结果源于本文所述的先前未观察到的热力学平衡。
