Abstract
A two step deallylation scheme using (bis(methyldiphenylphosphine)) 1,5-cyclooctadiene) iridium (I) hexafluorophosphate and catalytic amounts of osmium tetroxide with trimethylamine N-oxide is used to deprotect allyl glycosides in the presence of an azide group at C-2. This method avoids the formation of intramolecular 1,3-dipolar cycloaddition products which are isolated during the deprotection using other procedures.
