## Abstract We report here on the synthesis of some novel non‐symmetrical substituted bisindolizines by 3+2 dipolar cycloaddition reaction. New compounds were prepared by the direct reaction of isolated non‐symmetrical substituted 4,4′‐bipyridinium bisylides with dimethyl acetylenedicarboxy late (D
