A reagent-controlled SN2-glycosylation for the direct synthesis of β-linked 2-deoxy-sugars.
J. Am. Chem. Soc. , (2014) The efficient and stereoselective construction of glycosidic linkages remains one of the most formidable challenges in organic chemistry. This is especially true in cases such as β-linked deoxy-sugars, where the outcome of the reaction cannot be controlled us... |
