The use of the new magnesium-derived hydride reagen for carbohydrate derivatives

Szabovik G., Medgyes A., Antal Z., Varga Z., Knott W., Liptak A.

Polish Journal of Chemistry

1999

vol. 73 nr 6

1003-1009

The magnesium hydride based reagent in THF solution is an excellent tool for the stereoselective reduction of different uloside derivatives. Sugar azides, sulfonyl esters give aminosugars and methylose derivatives without affecting other functionalities. Halogenated sugars or methylene derivatives are stable under these conditions. The reagent can be applied in the presence of a wide variety of blocking groups (acetals, benzyl and allyl ethers, imides, C=C bonds) generally used in the carbohydrate chemistry.
