Resum
This report describes two straightforward synthetic methodologies to obtain α-CF3-isoserine, a new α,α-disubstituted β-amino acid, from α-(trifluoromethyl)acrylic acid. The routes involve the synthesis of five-membered cyclic sulfates (using sulfuryl chloride) or sulfamidates (using the Burgess reagent) from the corresponding chiral diols, which are obtained by a catalytic asymmetric dihydroxylation (AD) reaction. © 2005 American Chemical Society.
