The biochemically important deoxysugar 1-deoxy-D-xylulose was synthesi
zed by improved methods. D-Tartaric acid is the starting material for
a synthesis which proceeds via the intermediacy of 2,3,4-tribenzyl-D-t
hreitol. Another, highly efficient route used the Sharpless asymmetric
dihydroxylation of 5-benzyloxy-3-penten-2-one as its key step. These
syntheses are especially useful for isotopic labeling. (C) 1998 Publis
