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

Cycloaddition of pyridiniumylides to α-chloroacrylonitrile give indolizines: the regioselectivity of the reaction can be rationalized in terms of nucleophilic attack by the ylides on the olefin.

Indolizines and pyrrolo[2,1-a]isoquinolines are synthesized by 1,3-dipolar cycloadditions of pyridinium benzotriazolylmethylides or isoquinolinium benzotriazolylmethylides with ethylenes and acetylenes.

An efficient strategy for the synthesis of indolizines from readily available starting materials via oxidative C-H functionalization and 5-endo-dig cyclization in one step has been demonstrated. This protocol represents wide substrate scope, high functional group tolerance, and selectivity. The structure of the product was confirmed by X-ray crystallographic studies. Ag2CO3 required of this tandem reaction can be recycled and reused after undergoing oxidative reaction. (C) 2014 Elsevier Ltd. All rights reserved.
