Abstract
A new application of organoiodine(III) is presented. Fully protected glycals are directly converted into 2, 3-dihydro-4H-pyran-4-ones by [hydroxyltosyloxy)iodo]benzene (Phl(OH)OTs, 1). The detailed study reveals that this conversion is independent of the relative stereochemistry as well as the nature of protection on the pyran ring. 3-O-Silyl groups are most smoothly converted into the keto group giving 2, 3-dihydro-4if-pyran-4-ones in yields up to 74%. In contrast, 4, 6-di-O-acetyl-3-deoxyglucal Polycoordinated Iodine.
