“…Furthermore, this strategy is also applicable to the synthesis of 2-deoxy-2-amino-glycosides using amine-protecting groups that can performN GP.H owever, care needs to be taken when using an N-acetyl group for NGP as the corresponding glycosyl oxazoline is ac ommonly formed byproduct, but can be avoided by using Lewis acid catalysis. [8] Alternatively,o ther amine protecting groups that can perform NGP such as phthalimido, tetrachlorophthalimido, trichloroacetyl, allyloxycarbonyl, and 2,2,2-trichloroethyloxycarbonyl can be used. [9] In contrast, the introductiono f1 ,2-cis glycosidic linkages is much more challenging and requires glycosyl donors having a non-assisting functionality at C-2.…”
