Synthesis of 2-nitroglycals from glycals using the tetrabutylammonium nitrate-trifluoroacetic anhydride-triethylamine reagent system and base-catalyzed Ferrier rearrangement of acetylated 2-nitroglycals.


PMID 23931299

Abstract

A reagent system comprising tetrabutylammonium nitrate-trifluoroacetic anhydride-triethylamine has been developed for the synthesis of 2-nitroglycals from various protected glycals. The base-catalyzed Ferrier rearrangement on tri-O-acetylated 2-nitroglycals has been reported for the first time. Reactivity of these nitroacetates and associated selectivity has been examined, and some of the products have been converted into 2,3-diamino-2,3-dideoxyglycosides and methyl N-acetyl-D-lividosaminide.
