for the construction of indolizines has been proposed from easily available pyridine derivatives and γ-bromo-crotonates via a metal-free tandem process. A variety of indolizine derivatives were synthesized undermildconditions. Noteworthy features of this synthetic strategy are short reaction time, using air as oxidant and mild reaction conditions.
