J. Kopf et al., 1-N,2-O-carbonyl-3,5-O-isopropylidene-1-N-[(2R)-2-methyl-3-oxopentanoyl]-alpha-D-xylofuranosylamine, ACT CRYST C, 55, 1999, pp. 1541-1542
The title compound, C15H21NO7, was synthesized as part of a study involving
the testing of new carbohydrate-derived chiral auxiliaries. Its solid-stat
e conformation and absolute configuration were determined. The R configurat
ion for the chiral centre at C-22, created during the synthesis, was deduce
d from knowledge of the absolute structure of the D-xylose moiety.
