A novel and efficient procedure for the preparation of 3-aryl-indolizine by 1,3-dipolar cycloaddition was established. The pyridinium salts were prepared from the corresponding pyridines and benzyl halides. In the presence of cesium carbonate, electron-deficient alkynes reacted with the pyridinium salts in 1,4-dioxane through 1,3-dipolar cycloaddition followed by an aromatization reaction to generate the corresponding 3-aryl-indolizines. This method features cheap reagents, a simple workup procedure, mild conditions, high regioselectivity and generating the desired products in moderate to high yield (34%~81%).

Key words: indolizine, 1,3-dipolar cycloaddition, electron-deficient alkyne
