Spacer-mediated synthesis of bis-spiroketal disaccharides: Nonsymmetrical furanose-pyranose difructose dianhydrides [Article]
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 ...
Chemical and Enzymatic Approaches to Carbohydrate-Derived Spiroketals: Di-D-Fructose Dianhydrides (DFAs) [Article]
(MDPI AG, 2008)
Di-D-fructose dianhydrides (DFAs) comprise a unique family of stereoisomeric spiro-tricyclic disaccharides formed upon thermal and/or acidic activation of sucrose- and/or D-fructose-rich materials. The recent discovery of ...
