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

Two new methods of synthesizing indolizidines via ring-closing metathesis (RCM) have been developed. One method utilizes an alkene-isomerization, and the other method uses N-vinylation of an amide as the key step. Indolizidine 167E and many derivatives have also been synthesized.
