A series of acid-cleavable ester-type protectinggroups, with acid-sensitivity profiles parallel to those of 2-naphthylmethyl (NAP) or p-methoxybenzyl (PMB) ether, were designed and TFA in toluene was identified as a technically simple and effective deblocking cocktail for their global removal in the context of oligosaccharidesynthesis.
