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.
enantiomerically pure aziridinylmethyl azide is described that can be transformed to the corresponding triazole by a copper-catalysed [3+2] alkyne cycloaddition reaction. The transformation of these intermediates into triazolylalanine-type derivatives by aziridine ring-opening reactions is also described. copper catalyst - 1,2,3-triazole - aziridine - cycloaddition - ring-opening reaction - alanine
