Recent synthetic efforts in the construction of oligosaccharides, glycoproteins, glycolipids and other glycoconjugates containing a variety of 2‐amino‐2‐deoxy sugars have led to the development of new methods for nitrogen protection. These new nitrogen‐protecting groups have been removed from substrates using mild and often chemoselective conditions. In this microreview, the preparation, present uses, and deprotection of amino sugar derivatives employing these new agents are described. Applications of phthalimides with electron‐withdrawing groups including the tetrachlorophthaloyl (TCP), dichlorophthaloyl (DCPhth), dithiasuccinoyl (Dts), N‐pent‐4‐enoyl and N,N‐diacetyl functionalities are discussed.
