Abstract
The (2-benzyloxyphenyl)acetyl group has been identified as a new protecting group for hydroxyl functions. Various alcohols could be easily protected with high yields, and deprotection was achieved by a relay approach using Pd/H2 in combination with 1,8-bis(dimethylamino)naphthalene, conditions that are orthogonal to ester groups. The new protecting group is stable in glycosylation reactions demonstrating an effective neighboring group participation leading to the exclusive formation of 1,2-trans glycosides and glycosyl esters.
