Six optically active oxide propane monomers (1m-6m) were synthesized in a very facile way. The monomers were polymerized using potassium hydroxide (KOH) as an initiator to afford the corresponding polyethers (1p-6p). The polyether (R)-1p (specific rotation, [α]36525=+331) exhibited optical rotation as large as fourfold that of the monomer (R)-1m ([α]36525=-10). The specific optical rotation, circular dichroism (CD) and ultraviolet (UV)-visible spectra data showed that the obtained polymers can keep a prevailing helicity of the backbone in solution.
