An efficient method for the synthesis of N-Cbz-β-aminoalkanesulfonamides was described. N-Cbz-β-aminoalkanesulfona-mides were readily prepared in good yields from a variety of amino alcohols, including optically active ones, via N-Cbz protection with benzyl chloroformate, Mitsunobu esterification reaction with thiolacetic acid, N-chlorosuccinimide oxidation, and ammonolysis process.
