2-Nitro sugar derivatives bearing an axial nitro group were proved to be thermodynamically more stable than the corresponding 2-epimers, bearing an equatorial nitro group.
Methyl 4,6-O-benzylidene-2-C- and 3-C-cyano-2,3-dideoxy-D-erythro-hex-2-enopyranosides and -2-enitols were prepared and their epoxidation was performed. (C) 2007 Elsevier Ltd. All rights reserved.
