Various substituted taurines have been synthesized expeditiously and practically in satisfactory to good yields directly from amino alcohols using a two-step, one-pot procedure, in which the amino alcohols undergo sulfuric acid esterification and subsequent sodium sulfite substitution. Treatment of amino-substituted secondary alcohols using the same procedure gave 2-substituted or 1,2-di-substituted

mechanistic proposal, a new and rapid asymmetricsynthesis of (R)- and (S)-2-aminoalkanesulfonic acids from chiral amino alcohols was developed. Chiral amino alcohols were converted to chiral aziridines through the Wenker method or Mitsunobu reaction and the resulting aziridines were reacted with sodium bisulfite to produce chiral α-amino alkanesulfonic acids.
