3,4-Bis(O-tert-butyldimethylsilyl)-6-O-tosyl-D-glucal: A Probe for the Mechanism of the Iodine(III)-Promoted Allylic Oxidation of Glycals

The reaction of 3,4-bis(O-tert-butyldimethylsilyl)-6-O-tosyl-D-glucal 4 with the Koser reagent unexpectedly afforded tetrahydrofurfural 6 as well as 2,3-anhydropyranose 7 as major products.This unprecedented, stereoselective transformation helps to gain further insight into the mechanism of the well-documented hypervalent iodine-promoted allylic oxidation of cyclic enol ethers.A novel chemoenzymatic method for the preparation of glucal 4 in high yield is presented. - Keywords: 2,3-Anhydropyranose; Glycal; Hypervalent iodine
