The 2-O-[3-(2‘-benzyloxyphenyl)-3,3-dimethylpropanoate] and 2-O-[3-(2‘-benzyloxy-4‘,6‘-dimethylphenyl)-3,3-dimethylpropanoate] esters enable the synthesis of a range of β-glucosides and α-mannosides through neighboring participation in excellent yield, and are removed by hydrogenolysis in concert with the cleavage of benzyl esters in the presence of other esters making them particularly well suited to the stereocontrolled synthesis of glycosyl esters.
