Abstract
We have developed a simple method for the deprotection of allyl groups used as a protective group for the anomeric oxygen on a sugar moiety by employing tetrakis(triphenylphosphine) palladium in acetic acid. This method is applicable for not only simple but also complex allyl glycosides, such as natural lipid A intermediates and other important lipid A intermediates. Further, this method would be useful for large-scale preparation.
This study developed a simple method for deprotecting allyl groups on sugar moiety anomers using tetrakis(triphenylphosphine) palladium in acetic acid, applicable to both simple and complex allyl glycosides.
