Various 2-substituted indolizines can be directly and selectively lithiated in the 5 position and subsequent reactions with different electrophiles lead to some novel classes of indolizines. In particular, previously unknown 5-formyl- and 5-iodoindol

(Aza)indolizines reacted with ethyl propiolate regioselectively forming (aza)[2.2.3]cyclazines. The Sonogashira reaction of 5-iodo(aza)-indolizines and acetylenes led to 5-ethynyl(aza)indolizines. In the case of indolizine derivative the by-product w
