Free Radic. Biol. Med. 28(2) , 183-92, (2000)

This study investigated the ability of the yeast Saccharomyces cerevisiae to synthesize ascorbate and its 5-carbon analogue erythroascorbate from a variety of precursors, and their importance as antio...

De novo asymmetric syntheses of C-4-substituted sugars via an iterative dihydroxylation strategy.

Carbohydr. Res. 341(10) , 1505-21, (2006)

A short and highly efficient route to various C-4 substituted sugar lactones has been developed. The key to the overall transformation is the sequential osmium-catalyzed dihydroxylation reaction of su...
