(2-nitrophenyl)acetyl (NPAc) group for the protection of hydroxyl functions is reported. (2-Nitrophenyl)acetates are readily prepared starting from the commercially available, inexpensive (2-nitrophenyl)acetic acid, and these esters are stable under a series of common carbohydrate transformations. The NPAc group can be removed selectively using Zn and NH4Cl without affecting a series of common protecting groups
