Two beta-(alkyl)-beta-hydroxy-alpha-amino acids [alkyl = But, BnO-(CH2)(3)-] have been synthesized by a sequence based on Sharpless asymmetric dihydroxylation. The key sulfate intermediates were prepared from enantiomerically enriched diols by direct treatment with sulfuryl chloride. The scope and the appropriate conditions for sulfate formation have also been studied. (c) 2005 Published by Elsevier Ltd.
