3-Unsubstituted indolizine not only exhibits a variety of important biological activities, but also is a kind of important intermediate in organic synthesis. A transition metal free method for synthesizing 3-unsubstituted indolizines from pyridines, 2-chloroacetic acid and electron deficient alkenes has been invented in this paper. The designed products were obtained via oxidative dehydrogenation and decarboxylation reactions, and 2,2,6,6-tetramthyl-1-piperidinyloxy (TEMPO) was used as an oxidant. This method featured simple procedure, easy available starting materials and transition metal free conditions.

Key words: indolizine, 2,2,6,6-tetramthyl-1-piperidinyloxy, 1,3-dipolar cycloaddition, transition metal free reaction, dehydroaromatization
