The reaction of chiral 1-aminoalkylepoxides with CO2, generated from acidic treatment of an aqueous solution of NaHCO3 at room temperature, efficiently afforded enantiopure cyclic carbonates with total selectivity. Carbonates were readily transformed into the corresponding diols by reaction with LiAlH4 or by basic hydrolysis.
