Here we report a high-yielding method for the regioselective reductive ring opening of 4,6-O-benzylidene acetals of hexapyranosides using inexpensive and robust HClO4-SiO2 as the acidic catalyst and triethylsilane as the hydride dono
4,6-O-[1-cyano-2-(2-iodophenyl)ethylidene] acetals. Improved second-generation acetals for the stereoselective formation of β-D-mannopyranosides and regioselective reductive radical fragmentation to β-D-rhamnopyranosides. Scope and limitations

The [1-cyano-2-(2-iodophenyl)]ethylidene group is introduced as an acetal-protecting group for carbohydrate thioglycoside donors. The group is easily introduced under mild conditions, over short reaction times, and in the presence of a wide variety of oth
Chemical synthesis of (4,6-Pyr)-Gal β1→4GlcNacβ1→3Fucβ1→OMe: A pyruvated trisaccharide related to the cell aggregation of the sponge Microciona prolifera

4,6-O-[(R)-1-carboxylethylidene] Galβ1→4GlcNAcβ1→3Fucβ1→OMe, a pyruvated trisaccharide unit involved in the aggregation factor of the marine sponge Microciona prolifera, was synthesized stereospecifically and unambiguously employing thioglycosides as glycosyl donors to construct glycosidic bonds.
