The syntheses of 1,2:4,5-di-O-cyclohexylidene-β-D-fructopyranose and 1,2:4,5-di-O-cyclohexylidene-β-D-eryrtro-hexo-2,3-diulopyranose were improved. A method for the separation of isomeric oximes of diulose was developed, and their structures were established by ¹³C NMR spectroscopy. 3-Amino-3-deoxy-1,2:4,5-di-O-cyclohexylidene-β-D-psycopyranose was obtained.
