Resumen
Herein we describe the synthesis of the two enantiomerically pure 3-amino-2-hydroxy-2-methylpropionic acids - (S)- and (R)-α-methyl isoserines - starting from the chiral diols (S)- and (R)-2,3-dihydroxy-N- methoxy-2,N-dimethylpropionamides, respectively, which were obtained by Sharpless asymmetric dihydroxylation (AD) of the olefin N-methoxy-2,N- dimethylacrylamide with AD-mix α or β as chiral catalytic ligands. © 2003 Elsevier Ltd.
