## Nucleophilic addition-reactions of the title compound, prepared from the corresponding 3-nitrohex-2-enitol, were investigated under kinetically controlled conditions; such sterically bulky nucleophiles as tert-butyl peroxide and 2,4-pentanedionate ions (except in 1,Cdioxane) were found to enga
4,6-Di-O-acetyl-2,3-dideoxy-D-erythro-hex-2-enopyranose (4,6-di-o-acetyl-D-pseudoglucal), prepared from 3,4,6-tri-O-acetyl-1,5-anhydro-2-deoxy-D-arubinohex-1-enitol (tri-0-acetyl-D-glucal), was condensed, by catalysis with boron trifluoride, with an equivalent of the original glycal, to give crystal
