efficiently prepared by direct C-3 arylation of indolizines using sodium arylsulfinates and arylsulfonylhydrazides. Pd-catalyzed desulfitative C-3 arylation with sodium arylsulfinates was achieved with the assistance of peroxides, and the catalytic efficiency was promoted by N-containing ligands. Arylsulfonylhydrazides were also successfully applied in Pd-catalyzed desulfitative C-3 arylation with indolizines

borylation of indolizines has not previously been reported and in this communication, we describe our preliminary efforts to apply this chemistry to this scaffold and contrast this approach to directed metalation. Through these methodologies were possible obtain a library of substituted indolizines functionalized in both pyridinic and pyrrole ring.
