Steric Effects Are Not the Cause of the Rate Difference in Hydrolysis of Stereoisomeric Glycosides
Jensen, Henrik Helligso,Bols, Mikael

(Equation presented) A long-lived and plausible explanation as to why glycosides with axial substituents are more reactive than those with equatorial substituents was given in 1955 by Edward based on sterical hindrance being relieved in the transition state. Using model compounds 5, 6, 8, and 10, we here show conclusively that sterical hindrance not is the controlling factor in glycoside hydrolysis.

A conformational analysis of methyl α-C-lactoside (5) is carried out (Table 1), which suggests the preferred solution conformation of 5 to be described as a mixture of conformers A (φ = 300°; ψ = 60°) and B (φ = 300°; ψ = 300°) to a first approximation. A
Spiroketal Synthesis. - A Case of Intramolecular Glycoside Bond Formation
Preuss, Rainer,Jung, Karl-Heinz,Schmidt, Richard R.
, p. 377 - 382 (2007/10/02)
From 4-O-unsubstituted glucose derivatives 1a, b the 4-hydroxymethyl-substituted glucose derivatives 9a, b were obtained via oxidation to the ketone, Wittig reaction with methylenetriphenylphosphorane, borane addition, and subsequent oxidation to yield th
Synthesis of α-Methyl 1',2'-Dideoxycellobioside: A Novel C-Disaccharide

Bromonium ion induced 6-endo-trig cyclizations of E olefins derived from D-arabinose provide a stereoselective route to 2'-deoxyglucono-β-C-glycosides.Use of δ-alkenols containing allylic isopropylidenes (i.e., 1) prevents formation of furan products due
