Helically chiral spirocyclic P3 phosphazenes were designed as a novel family of chiral organosuperbases. The newly designed chiral P3 phosphazenes were synthesized from commercially available sources in several steps and characterized by X-ray crystallographic analysis of their onium salts. The optically pure P3 phosphazenium salt was obtained by using preparative chiral stationary phase HPLC and the absolute configuration of the helical chirality was determined.
