1-N,2-O-Carbonyl-3,5-O-isopropylidene-1-N-[(2R)-2-methyl-3-oxopentanoyl]-α-D-xylofuranosylamine

Abstract

The title compound, CIsH21NOT, was synthesized as part of a study involving the testing of new carbohydrate-derived chiral auxiliaries. Its solid-state conformation and absolute configuration were determined. The R configuration for the chiral centre at C-22, created during the synthesis, was deduced from knowledge of the absolute structure of the o-xylose moiety.
