L-streptose is a branched monosaccharide similar to apiose in structure. L-streptose is one of the sugars in streptomycin, an aminoglycoside antibiotic that has toxic effects in the kidney and other side effects.
L-streptose has been prepared from a carbohydrate derivative. The protected monosaccharide was reacted with an organo-lithium sulfur compound and then catalytically hydrolyzed to produce L-streptose.
