Sonogashira Reaction of the Indolizine Ring. -2-Tert-butyl-5-iodoindolizine is successfully coupled with aryl and alkylacetylenes as well as trimethylsilylacetylene. A corresponding transformation of 5-bromo or 2-phenyl substituted substrates fails as well as an attempted cyclization of the products to cyclo[3.2.2.]azines. -(SHADRIN, I. A.; RZHEVSKII, S.
