Synthesis of sugar oxazolines by intramolecular Ritter-like reaction of D-fructose precursors
(2004)
Treatment of D-fructopyranose and D-fructofuranosc 1,2-O-acetonide derivatives with triflic acid in the presence of a variety of nitriles results in the formation of fused or spiro 2-oxazolines. The reaction implies (i) ...

Spacer-mediated synthesis of bis-spiroketal disaccharides: Nonsymmetrical furanose-pyranose difructose dianhydrides
(2007)
The stereochemical outcome of the dimerization reaction of D-fructose, leading to tricyclic bis-spiroketal systems, can be tuned by inserting a xylylene template between the reacting moieties. Spirocyclization becomes then ...
