When anomeric effects collide
Rotational coordinates about the C(3)–O(4) bonds of 2,4-dioxaheptane (DOH) and 2,4,6-trioxaheptane (TOH) are compared at correlated levels of electronic structure theory for gauche and trans orientations of the O(2)–C(3) bonds. TOH has overlapping anomeric effects, while DOH does not. The overlapping stereoelectronic effect shows its largest impact on the length of the O(2)–C(3) bond, which is ...
متن کاملAnomeric Hydroperoxides; Synthesis, Enantioselective Epoxidation
Some time ago we reported the oxidation of 2,3-unsaturated hexopyranosides and 2-Cmethylene glycosides with hydrogen peroxide in the presence of molybdenum trioxide catalyst to give the corresponding anomeric hydroperoxides 1-5. Relatively stable hydroperoxides 1-5 were used for enantioselective oxidation of prochiral alcohols and sulfides in the presence of Ti(OiPr)4 with stereoselectivities v...
متن کاملThe substrate and anomeric specificity of fructokinase.
Fructokinase from beef liver is shown to be specific for the /3-furanose anomer of D-fructose (and the LY anomer of Lsorbose) by showing that certain 2,5-anhydroalditols are substrates, while other 2,5-anhydro compounds, 2,6-anhydro-D-mannitol, and 2,6-anhydro-D-glucitol are not. Km and Ir,,, values relative to D-fructose at pH 7.5, 25”, 4 mu MgATP are 2,5-anhydro-D-mannitol (1.7 mu, 1.97); 2,5...
