Enantiomeric (R)- and (S)-2-aminopropanesulfonic acids, 4a and 4b, were prepared in good yields and high enantiomeric purities (>99% ee) from (S)-5a and (R)-1-amino-2-propanol 5b respectively, using a four step synthesis. The absolute configuration of(S)-enantiomer 4b was established by X-ray analysis. (C) 1996 Elsevier Science Ltd

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.
