title: Efficient synthesis of sugar oxazolines from unprotected N-acetyl-2-amino sugars by using chloroformamidinium reagent in water.
abstract: Sugar oxazoline derivatives were directly synthesized from the corresponding N-acetyl-2-amino sugars in aqueous media by using a chloroformamidinium-type dehydrating reagent. The present method could successfully be applied to chito-oligosaccharides, saccharides with acid functions, and a complex-type oligosaccharide derived from a glycopeptide.
