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.

The stereoselective and short-step synthesis of N-protected allo-carnosadine, ent-carnosadine, and carnosadine lactam was accomplished from a common cyclopropane intermediate. The inter-intramolecular double alkylation of diethyl malonate with an opticallyactive 2-methylaziridine derivative gave the key cyclopropane in excellent yield and optical purity. The following monohydrolysis of the diester
