Synthesis of Indolizines via Cycloisomerization Reactions

A regiodivergent transition metal-catalyzed synthesis of differently substituted indolizines vas recently elaborated on by Gevorgyan and co vorkers. Thus, pyridyl-substituted cyclopropenes 356 vere smoothly cycloisomerized in the presence of 

Alternatively, regioisomeric azametalaqrcles 361 and 364 may arise directly from a regioselective oxidative addition process in cyclopropene 356.
