Some bicyclic imides and triazole compounds have separately shown biological activities. We now combine these two structural features into the synthesis of triazolyl‐substituted quinolizidine imides 21. Dihydro‐2‐pyridone compound 15, obtained previously from the aza‐Diels‐Alder reaction, was first oxidized to the sulfone 16 which was effectively converted to the azide 17. Further click chemistry of
一些双环酰亚胺和三唑化合物已分别显示出生物学活性。现在,我们将这两个结构特征结合在一起,合成三唑基取代的喹oli嗪酰亚胺21。先前从aza-Diels-Alder反应获得的二氢-2-吡啶酮化合物15首先被氧化为砜16,然后有效地转化为叠氮化物17。化合物17与末端炔的进一步点击化学反应是区域特异性地提供1,4-二取代的三唑18a-c。然后用Bu 3 SnH / AIBN进行顺序脱甲苯基化,N-烯丙基化和闭环复分解(RCM)反应,从而提供双环酰亚胺21a-b。
